AP23489765 "Improvement of technology for processing oxidized ores based on new non-toxic sulfur-containing reagents"

Relevance

The proposed technology for processing hard-to-enrich polymetallic ores using environmentally friendly reagents will make it possible to rationally use mineral raw materials, increase the economic potential of Kazakhstan, create new jobs, and improve the skills of enterprise personnel.

Purpose

Development of technology for processing hard-to-enrich polymetallic raw materials using environmentally friendly reagents. The proposed technology using environmentally friendly reagents will improve the technological performance of flotation enrichment of difficult-to-enrich polymetallic raw materials containing precious and rare metals by 3-5%, while reducing the consumption of the proposed reagents by 10-20%.

Expected and achieved results

For the first time, ecologically safe sulfur-containing reagents will be used as sulfurizing agents for the effective processing of difficult-to-concentrate polymetallic ores. As sulfur-containing reagents, polysulfides of alkali and alkaline earth metals, derived from technical sulfur and metal oxides, will be used. This will replace the toxic sodium sulfide while simultaneously improving the extraction rates of non-ferrous metals. The research results demonstrate that the proposed reagents provide higher flotation selectivity and significantly increase the recovery of valuable components, opening new prospects for the processing of polymetallic raw materials.
