View →Chemnergy supplies the acids and reagents used to dissolve target metals from ore in heap, tank and in-situ leaching — principally bulk sulphuric acid for oxide copper and cobalt leaching, alongside supporting reagents for specific leach chemistries. Talk to us about your leach circuit's reagent and volume requirements.
View →Consistent pulp pH is critical to flotation selectivity and leach efficiency. We supply the standard pH-adjusting reagents used across African mining operations — including soda ash for raising pH ahead of flotation and lime/magnesium oxide for neutralisation downstream — sized to your circuit's consumption rate.
View →Sulphide ores — the copper, cobalt, gold and zinc sulphides common across the Copperbelt and Central African mining regions — are typically concentrated by froth flotation. Chemnergy supplies the full collector, frother, modifier, depressant and activator suite used in sulphide flotation circuits.
View →Oxide ores are generally not amenable to flotation and are instead processed by acid leaching followed by solvent extraction and electrowinning (SX-EW). Chemnergy supplies bulk sulphuric acid and supporting process chemicals for oxide copper and cobalt operations.
View →From flotation of sulphide-associated gold through to cyanide destruction ahead of tailings discharge, Chemnergy supplies the reagents gold processing plants depend on — including flotation collectors and sodium metabisulfite (SMBS) for the SO2/air cyanide-destruction process.
View →Chemnergy supplies the full reagent suite for copper processing: xanthate collectors for sulphide flotation, and bulk sulphuric acid for oxide leaching and SX-EW electrolyte make-up, backed by bonded stock in Zambia's Copperbelt region.
View →The Copperbelt's copper-cobalt ores require both flotation collectors for sulphide cobalt (carrollite) and bulk acid for oxide cobalt leaching. Chemnergy supplies both from Zambian stock, along with magnesium oxide for downstream neutralisation.
View →Settling and clarifying process water, tailings and effluent requires reliable flocculants and coagulants. Chemnergy sources these on request to match your thickener and clarifier duty, tonnage and water chemistry.
View →Mine sites need to treat process water, potable water and effluent to the same standard as any municipal system, at industrial scale. Chemnergy supplies coagulants, flocculants, pH adjusters and disinfection chemicals for mine-site water treatment.
View →Solvent extraction and electrowinning (SX-EW) is the standard route for oxide copper and cobalt recovery. Chemnergy supplies bulk sulphuric acid for electrolyte make-up and leaching, and can source specialty SX reagents on request.
View →Haul roads, stockpiles and crushing/screening plants generate dust that affects safety, equipment life and community relations. Chemnergy sources dust-suppression chemicals and can advise on application rates for your site conditions.
View →Responsible tailings and wastewater management requires reliable neutralisation, precipitation and flocculation chemistry. Chemnergy supplies magnesium oxide and sodium hydrosulfide for metal precipitation and neutralisation, plus flocculants sourced on request.
View →Beyond flotation and leaching, metallurgical plants rely on a range of supporting process chemicals for grinding aids, corrosion control and reagent conditioning. Chemnergy can source these to specification from our international supplier network.
View →Alongside processing chemicals, Chemnergy supplies bulk industrial minerals and raw materials used across mining and adjacent industries, sourced and delivered at the volumes mine sites require.
