The ultimate proving ground - Solid Ground : Solid Ground

30/08/2019  The sulphide circuit consists of a primary crusher, a secondary crusher and three tertiary crushers in a closed circuit, for the production of a product approaching 98 percent smaller than ¼” (6.4mm) to supply the ball mills. “The tertiary line is the backbone of the sulphide plant,” Carrasco says.

Sulphide Flotation - an overview ScienceDirect Topics

The Platsol™ process was originally developed in Canada for the treatment of flotation sulfide concentrate for Polymet Mining Company in Minnesota and subsequently tested on other PGM concentrates. This process involved codissolution of base metals (copper and nickel), gold, and PGMs via addition of chloride to the autoclave.

Lime use and functionality in sulphide mineral flotation ...

01/11/2019  Sulfide minerals are, by nature, acid to varying degrees causing the milled pulp to have a pH ranging from 4 to 8 depending on the sulphide and gangue mineral composition of the ore. In most circuits the bulk of the lime addition occurs in this location. Lime is added to avoid acid pH conditions that could lead to metal dissolution effects that would impede flotation recovery, and has been ...

Sulphide Gold Ore Treatment by Leaching and Flotation Process

Problem with gold recovery from sulphide ore: How may a mill get the maximum recovery of gold from a sulphide ore, at the least capital cost and at the same time obtain the highest net return. This latter point is most important. In many cases a gold mill using an all-cyanide flowsheet with fine grinding of all the ore will report very low gold content in the tailings particularly on an ...
