# Bio-flotation reagents for mining

Biosurfactant and plant-oil-derived frothers and collectors that replace petroleum-based alcohol, glycol and fatty-acid-derivative reagents in mineral froth flotation, sold by dedicated bio-based specialty-chemical producers (Locus Mining Solutions, Integrity BioChem, Godavari Biorefineries, NAQ Global) to mining operators rather than manufactured in-house by mine sites.

## Overview and value chain

Markers: [EC: US EPA chemical-substance oversight / EU REACH registration | OECD: Environmental biotechnology, Circular bioeconomy | Regulator: EPA (USA), REACH (EU)]

Bio-flotation reagents are biosurfactants and plant-oil-derived frothers, collectors and dispersants that replace petroleum-based alcohol, glycol or fatty-acid-derivative chemistry in mineral froth flotation — the process that separates valuable minerals from crushed ore by attaching them to air bubbles. Every confirmed producer here markets its product as a fermentation-derived or vegetable-oil-derived alternative to a specific incumbent fossil chemistry: Locus Mining's biosurfactants and bio-leaching compositions target gold-recovery leachate chemistry and mineral-flotation reagents, Integrity BioChem's TegraFroth targets alcohol and glycol frothers, Godavari Biorefineries' SOMFROTH is a sugarcane-derived frother targeting the same copper-flotation application as synthetic frothers, and NAQ Global's vegetable fatty-acid collectors target the petroleum-derived collector chemistry used in rock beneficiation. Two India-based (Godavari) and Brazil-founded-multinational (NAQ Global) producers sit outside the strict US/CN/EU header structure and are carried in the Leading Companies table rather than given a dedicated regional section, following the same non-triad precedent used elsewhere on this site — a reminder that this category's genuine commercial activity concentrates in the US, India and Brazil rather than in China or the EU, where this screening pass could not confirm a comparable bio-based commercial producer.

The key directions of bio-flotation reagents for mining are:
1. **Bio-based frothers:** fermentation- or plant-oil-derived frothing agents (TegraFroth, SOMFROTH) that replace synthetic alcohol and glycol frothers in the flotation process, the most directly substitutable reagent category since frother chemistry is a relatively narrow function.
2. **Biosurfactant flotation and recovery reagents:** broader biosurfactant chemistries (Locus Mining) applied across flotation reagents and leachate-based recovery processes, extending beyond frothing into the mineral-recovery chemistry itself.
3. **Vegetable-oil-derived collectors:** plant-oil-based collector chemistry (NAQ Global) that replaces petroleum-derived collectors used to attach target minerals to air bubbles during flotation, a distinct reagent function from frothing.
4. **Bio-based surfactants for adjacent industrial and mining applications:** biosurfactant product lines (Integrity BioChem's TegraSurf) sold into broader heavy-industrial-and-institutional (HI&I) applications alongside the mining-specific frother line, sharing the same underlying biosurfactant chemistry across a wider industrial customer base.

### Value chain levels

| Level | Description | Key inputs/outputs |
|:---|:---|:---|
| **Biosurfactant/feedstock fermentation or extraction** | Producing the biosurfactant via microbial fermentation or extracting the plant-oil feedstock (sugarcane, vegetable oil). | **In:** Fermentation feedstock or plant oil.<br>**Out:** Biosurfactant or bio-based reagent precursor. |
| **Reagent formulation** | Formulating the precursor into a frother, collector or dispersant product for a specific ore type and flotation circuit. | **In:** Biosurfactant/bio-based precursor.<br>**Out:** Formulated flotation reagent. |
| **Mine-site delivery and dosing** | Delivering the reagent to the mine site and dosing it into the flotation circuit at the specified rate. | **In:** Formulated reagent, mine-site logistics.<br>**Out:** Reagent dosed into active flotation circuit. |
| **Flotation circuit performance testing** | Testing mineral recovery, grade and selectivity against the incumbent reagent's baseline performance. | **In:** Dosed flotation circuit.<br>**Out:** Verified recovery/grade/selectivity performance data. |
| **Ongoing reagent optimization** | Adjusting dosing and formulation based on ore variability and performance data over the life of the mine. | **In:** Performance data, ore variability.<br>**Out:** Optimized, sustained reagent performance. |
| **Mineral concentrate output** | Producing the final mineral concentrate that is sold or further processed. | **In:** Optimized flotation output.<br>**Out:** Mineral concentrate for sale or downstream processing. |

Cross-cutting technologies of the sector:
- **Direct fossil-reagent substitution framing:** every confirmed producer positions its product as a drop-in replacement for a specific incumbent petrochemical reagent (frother, collector or leachate chemistry) rather than a novel flotation mechanism, making performance-parity testing against the incumbent the central commercial proof point.
- **Fermentation and plant-oil dual feedstock routes:** the category splits between microbial fermentation-derived biosurfactants (Locus Mining, Integrity BioChem) and directly extracted plant-oil feedstock (Godavari's sugarcane-derived SOMFROTH, NAQ Global's vegetable fatty-acid collectors), two distinct production routes converging on the same substitution goal.
- **Biodegradability as the commercial sustainability claim:** every confirmed producer markets improved biodegradability relative to the incumbent fossil reagent as the core environmental proof point, distinct from a downstream-product bio-content claim since the reagent itself does not end up in the mineral concentrate.

## US

The United States hosts two confirmed producers spanning biosurfactant-based flotation/recovery reagents and bio-based frothers.

### Biosurfactant and bio-based frother producers
- **Locus Mining Solutions:** a division of Locus Fermentation Solutions (Solon, Ohio) offering carbon-neutral biosurfactant additives as flotation reagents, alongside patented bio-leaching compositions for gold-recovery leachate chemistry; a 2022 S&P Global Energy Awards finalist for its decarbonizing mining reagents.
- **Integrity BioChem:** produces TegraFroth, a bio-based frother positioned as a sustainable replacement for traditional alcohol and glycol frothers in mineral flotation, alongside TegraSurf, a related bio-based surfactant line for broader heavy-industrial and institutional applications.

## CN

China has an active mineral-flotation-chemicals manufacturing sector, but this screening pass could not confirm a China-headquartered bio-based producer.

### A real flotation-chemicals industry, confirmed synthetic rather than bio-based
This pass found an active Chinese mineral-flotation-chemicals manufacturer (Zhejiang Xinyong Biochemical among others, offering dithiophosphate collectors and other froth flotation reagents), but confirmed none of it as bio-based: the products found are described in vendor-own content as synthetic organic compounds engineered through chemical synthesis, not fermentation-derived or plant-oil-derived chemistry. This section is left descriptive of that finding — a real Chinese flotation-chemicals industry exists, but this pass could not confirm a China-headquartered producer selling a bio-based reagent meeting the same standard applied to the US, India and Brazil producers above.

---

## EU

Europe has an established industrial-minerals flotation-reagent producer and an active research consortium, but this screening pass could not confirm a bio-based commercial producer meeting the sourcing bar applied elsewhere.

### A biodegradability claim short of a bio-based sourcing claim
This pass found a German industrial-minerals flotation-reagent producer (EKOF, Bochum) whose RESANOL reagent line is described on its own site as "largely biodegradable when diluted" rather than as bio-based or derived from a renewable feedstock — a biodegradability claim about the finished reagent, not a sourcing claim about its origin, and therefore not confirmed to the same bio-based standard as the US, India and Brazil producers above. A Fraunhofer IGB-led "Alliance Biosurfactants" research consortium is active in Germany, indicating research momentum in the space, but no confirmed commercial EU flotation-reagent producer meeting the bio-based bar was found this pass.

## Tech stack and innovations

The stack centers on direct substitution for a specific incumbent petrochemical reagent function (frother, collector or leachate chemistry) via one of two feedstock routes — microbial fermentation or plant-oil extraction — with performance-parity testing as the shared commercial proof point.

1. **Function-Specific Substitution Rather Than a Novel Flotation Mechanism:**
   - Every confirmed producer targets a specific, narrow reagent function already well-defined in conventional flotation chemistry — frothing (TegraFroth, SOMFROTH), collecting (NAQ Global's vegetable fatty-acid collectors) or broader recovery/leachate chemistry (Locus Mining) — rather than proposing an entirely new flotation mechanism.
   - This narrow-substitution framing is what makes the products directly comparable to an incumbent reagent on recovery, grade and selectivity metrics, rather than requiring a mine operator to redesign its flotation circuit.
2. **Fermentation Versus Plant-Oil Feedstock as Parallel Production Routes:**
   - Locus Mining and Integrity BioChem both derive their biosurfactants via microbial fermentation, while Godavari Biorefineries (sugarcane) and NAQ Global (vegetable oil) extract their reagent precursor directly from plant feedstock — two distinct upstream production routes that converge on the same downstream substitution goal.
   - This means evaluating a "bio-based flotation reagent" claim should include checking which feedstock route underlies it, since fermentation-derived and plant-oil-derived reagents can have different cost structures and feedstock-availability risk profiles.
3. **Biodegradability as the Commercial Environmental Claim, Not a Downstream Bio-Content Claim:**
   - Because flotation reagents are consumed in the process rather than ending up in the mineral concentrate itself, every confirmed producer's environmental marketing centers on the reagent's own biodegradability and lower toxicity relative to the incumbent fossil reagent, not a bio-based-content claim about the mined metal or mineral product.
   - This is a structurally different sustainability claim from most other categories on this site, where the bio-based content of the finished product itself is the claim — here it is entirely about the process chemistry's environmental footprint.

#### Stage 1: Biosurfactant/feedstock fermentation or extraction
The producer generates the biosurfactant via microbial fermentation or extracts the plant-oil feedstock, the stage where the two parallel production routes (fermentation versus plant-oil) diverge.

#### Stage 2: Reagent formulation
The precursor is formulated into a frother, collector or dispersant product engineered for a specific ore type and flotation circuit configuration.

#### Stage 3: Mine-site delivery and dosing
The formulated reagent is delivered to the mine site and dosed into the flotation circuit at a specified rate, typically alongside or in direct comparison to the incumbent fossil reagent it targets replacing.

#### Stage 4: Flotation circuit performance testing
Mineral recovery, grade and selectivity are tested against the incumbent reagent's baseline performance, the stage that generates the commercial proof point substantiating the bio-based reagent's substitution claim.

#### Stage 5: Ongoing reagent optimization
Dosing and formulation are adjusted based on ore variability and performance data over the life of the mine, a recurring technical-service relationship between the reagent producer and the mine operator.

#### Stage 6: Mineral concentrate output
The optimized flotation process produces the final mineral concentrate for sale or downstream processing — the reagent itself is consumed in the process and does not appear in the concentrate, which is why the sustainability claim centers on process biodegradability rather than product bio-content.
