Retreatment of Residues and Waste Rock

for many years. By 1936, 40% of the ore milled was still leached in sand treatment plants. Almost 20 million tons of sand per year was still deposited onto dumps. By 1946 this figure was considerably reduced and in that year only 13% oJ the ore, amounting to Get price

Petra Diamonds

Excavated ore is transported to a processing plant. The kimberlite is first crushed and then processed through the plant, which consists of a series of screens, jigs and scrubbers and a gravity pan or DMS plant to remove lighter particles and create a concentrate of heavy material, which includes the Get price

SVG resumed mining magnetite ore and producing magnetite concentrate at a rate of 2.2 dry metric tons per annum (Mt/a). Later, a debottlenecking initiative helped increase output to 2.8 dry Mt/a, but SVG wanted to investigate options for increasing capacity to 5.6 dry Mt/a. Get price

How and why do we produce gold and copper concentrates

1) Smelting: involves heating the concentrate to 1,200C to melt the valuable metals (gold, copper and silver) 2) Roasting: essentially 'cooking' the concentrate at 750C and isolating the gold, copper and silver by converting the sulphur in the sulphide minerals Get price

2013 News

The circuit relied on a traditional mill-float-mill-float (MF2) approach to partially liberate particles, followed by fine regrinding of concentrates to achieve a concentrate grade suitable for smelting. Separate treatment of the primary and secondary rougher concentrates allowed for separately-optimized cleaner flotation of fast and slow species. Get price
