Thionocarbamate collector is a liquid sulfide flotation reagent evaluated when a plant needs selective copper, copper-molybdenum or complex sulfide recovery. YuXing supplies a grade with ≥90% active ingredient. Final selection and dosage should be based on ore-specific laboratory work and a controlled plant trial.

Selective Copper and Complex Sulfide Applications
| Circuit | Why it may be evaluated | Data needed before selection |
|---|---|---|
| Copper sulfide flotation | Assess selective collection of valuable copper minerals | Mineralogy, oxidation, pH and current collector |
| Copper-molybdenum circuit | Test the required recovery-selectivity balance within the actual flowsheet | Target concentrate, separation stage and depressant scheme |
| Complex polymetallic sulfides | Evaluate selectivity where several sulfide minerals respond | Lead/zinc/iron mineral response and activation conditions |
| Cleaner or scavenger duty | Adjust recovery and concentrate quality by stage | Stage duty, circulating load and reagent carryover |

Thionocarbamate vs Xanthate and Dithiophosphate
| Collector | Typical evaluation focus | Important limitation |
|---|---|---|
| Thionocarbamate | Selective copper or complex sulfide response | Performance depends on ore and complete reagent suite |
| Xanthate | Established collecting strength in many sulfide circuits | Higher strength does not automatically mean better separation |
| Dithiophosphate | Alternative or complementary sulfide/precious-metal collection | Must be compared at equivalent circuit conditions |
Useful comparison pages include sodium butyl xanthate, ammonium dibutyl dithiophosphate and xanthate versus dithiophosphate.
How to Establish a Trial Range
- Record mineralogy, head grade, target mineral, grind size and process-water chemistry.
- Document pH, activator, depressant, frother and the incumbent collector.
- Run controlled bench tests with recovery and concentrate grade as paired outcomes.
- Observe froth mobility, entrainment, selectivity and any downstream effect.
- Define a controlled plant trial only after laboratory evidence and site safety review.
Do not copy a dosage from another plant. Even similar ore names can have different mineral associations, oxidation and water chemistry.
Supply, Documents and Quotation
Packaging and shipment arrangements are confirmed by quantity, destination and regulatory requirements. Available specification, SDS and batch documents depend on the producer and confirmed order. For a quotation, provide the ore type, target mineral, current reagent scheme, trial or annual volume, packaging, destination port and required documents.
Frequently Asked Questions
What is a thionocarbamate collector used for?
It is evaluated as a selective collector for copper, copper-molybdenum and complex sulfide ore flotation. Suitability depends on mineralogy and circuit conditions.
How is thionocarbamate different from xanthate?
Thionocarbamate may be tested where the circuit needs a different recovery-selectivity balance. Xanthates are widely used collectors, but neither family is universally better for every ore.
What dosage should a flotation plant use?
There is no universal dosage. Establish a test range from ore mineralogy, grind size, pH, water chemistry, flotation stage and the existing reagent suite.
What should be included in an inquiry?
Provide ore type, target mineral, current reagent scheme, trial or annual quantity, packaging, destination port and required documents.
