sulfide ores simple Solutions Just Right For You

16 06 2020Sulfide mineral any member of a group of compounds of sulfur with one or more metals Most of the sulfides are simple structurally exhibit high symmetry in their crystal forms and have many of the properties of metals including metallic luster and electrical conductivity Copper Ore Processing Methods Copper Ore Processing Methods Oxidized ores in which malachite azurite and chrysocolla are the predominant copper minerals that do not respond either to gravity or simple flotation methods Sulfidefilming of the carbonates followed by flotation of the filmed minerals or direct leaching followed by precipitation of the copper from the solution may be employed for

Comparison Of Oxide And Sulphide Copper Ore Deposits Copper Mining and Processing Processing of Copper Ores Copper processing is a complied process that begins with mining of the ore less than 1 copper and ends with sheets of 9999 pure copper called hodes which will ultimately be made into products for everyday most common types of ore copper oxide and copper sulfide undergo two

Sulfide Ore an overview | ScienceDirect Topics First application of the thin layer process on copper sulfide ores (chalcocite) contains about 1% Cu In 1994 the design capacity was of 75 000 tons/year which was increased to 80 000 tons/year subsequently Process modifications included irrigation using preheated raffinate solutions use of semiburied drippers bottom aeration and

Recovery of gold in sulfide ores has fallen into several categories First is froth flotation and second is cyanidation of the ores Using cyanide to recover gold from sulfide ores generally results in 30 to 35% recovery and the best I have heard of is around 50% recovery Read More

Rebellious Ores Sulfides Selenides And Tellurides In many locations where they had initially been recovering 90 of the assay values processing oxidized surface ore with the rebellious sulfide ores they were recovering less than 50 the rest of the precious metals in their ore simply flowed uselessly out from the mill and into the tailings pond
