Flotation Of Pgm Converter Slag

US4404022A Dore slag treatment Google Patents

A method is disclosed for treating dore slag resulting from smelting of a dore furnace charge by grinding such slag and then subjecting the obtained pulp to froth flotation in the presence of a suitable frother and collector to produce a precious metals concentrate which is then filtered and returned to the dore furnace with the next charge

milling and flotation of slow cooled copper slag

Copper Recovery Through Smelter Slag Flotation in Another aspect that can affect both the milling and flotation of CS is the cooling behavior of the slag Several researchers have reported that slow cooling of the slag can lead to an improvement in copper recovery because of the segregation of some valuable elements such as copper silver and I NGENIER IA E I NVESTIGACIONV OL 41 N O 1

II1PGM in South Africa Generally the ore is treated by crushing grinding and flotation to produce a concentrate which is molten in a furnace to produce two immiscible melts a denser sulphide melt matte and a less dense silicate melt slag The slag and matte phases are tapped through separate furnace tap holes the slag is discarded

Recovery of metal values from copper slags by flotation

Feb 01 2007 A fayalitictype of ancient copper slag containing 124 Cu 053 Co and 5316 Fe were subjected to an experimental study Two different routes were followed to recover the metal values The first route was roasting the slag with pyrite followed by leaching The second route was flotation of the slags roasting of the flotation tailings with

Air Granulation of Copper Slags for Iron Silicate

Jan 01 2019 Based on PGM converter slag granulation performance parallels to copper slag granulation are drawn and fullscale operation for copper slag is modelled using computational fluid dynamics CFD INTRODUCTION Typical slag management practices in the copper industry include dumping slow air cooling and water granulation as shown in Figure 1

Platinum is produced in South Africa by Amplats Impala

The slag from this operation has a PGM content too high 25 to 35 gt to be discarded so it is granulated and returned to the flotation circuit for the recovery of the PGMs Lime or limestone is sometimes used as a flux to improve the compatibility of the slag with the basic refractory lining

Flotation of copper sulphide from copper smelter slag
