FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

FLOWSHEET OPTIONS CRUSHING FOLLOWED BY DUMP OR HEAP LEACHING WITH CYANIDE This method of gold recovery is the preferred method for treating low-grade gold ores because of its low cost. Between 10-20% of the gold recovered each year from primary sources is extracted by this technique. The advantages of this process are: • Simplicity

WO2007115377A1 Process for recovery of antimony and

A process for recovery of antimony and metal values from antimony- and metal value-bearing materials is provided. A coarse (typically >250-µm) concentrate of the antimony- and metal value-bearing materials is provided. The coarse concentrate is then subjected to a process for selective recovery of antimony in the form of solid antimony or an antimony containing solution.

Antimony Recovery from End-of-Life Products and Industrial

Feb 08, 2016 Antimony has become an increasingly critical element in recent years, due to a surge in industrial demand and the Chinese domination of primary production. Antimony is produced from stibnite ore (Sb2O3) which is processed into antimony metal and antimony oxide (Sb2O3). The industrial importance of antimony is mainly derived from its use as flame retardant in plastics, coatings, and
