The feasibility ofelutionwithsimultaneous electrowinningwas demonstrated in the laboratory. Completeelutionandgold recoverywere achieved in less than 5 h, with an average current efficiency of about 50%. Present address: Sastech Engineering Services, …
Flotation machine (also called flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc.
Stirring tank is suitable for mixing before flotation, for various metal and ores to adequately mix pharmaceutical and pulp, and it can also be used for mixing other non-metallic minerals.
Hongxing cone crusher is used for crushing ores and rocks and the advantages are reliable structure, high efficiency, easy adjustment and economy.
Milling equipment, mineral processing equipment and building materials equipment. And they are mainly used to crush coarse minerals like gold and copper ore, metals like steel and iron, glass, coal, gravel, etc.
Linear vibrating screen is widely used for screening any dry materials whose diameter is 0.074-15mm and the biggest feeding granularity is less than 20mm.
This series screen is always used in processing minerals such as ferrous metals including hematite magnet and nonferrous metals including lead, zinc, gold and silver, etc.
Electrowinninghas proved to be an effective and simple method for recoveringgoldfrom theeluate.Electrowinningis done simultaneously with theelution. The barreneluateis recycled to theeluanttank and is recycled for the nextelutionafter the reagents have been made up to their relevant concentrations.
