KCM has now developed a process to extract copper from the refractory ore stockpile. The company also produces several byproducts, including sulphuric acid produced from the smelting process, which is largely consumed in the leaching process. The new Nchanga smelter also has the capability to recover cobalt from copper concentrates.
The key principle of modern Process Mineralogy is to develop a single flowsheet that captures the range of processing needs of the main geomet units in the resource, and to deliver therefrom saleable, or treatable, final concentrates on a sustainable basis. For the samples tested to date, this has been achieved for the Kamoa project.
The objectives of the modular copper sulphate production plant concept are: To offer small and medium sized copper oxide concentrate producers an alternative process flow sheet to more conventional dense media separation (DMS) or artisanal hand sorting copper processing methodologies. In this respect, the copper sulphate route offers .

Flowsheet 1, the Conventional Circuit, is a simplified (and amended to include cobalt recovery) version of the metallurgical flowsheet that has been in use for many years at the Tailings Leach Plant at Nchanga, Zambia1. It provides the base case for this study and comprises a single train circuit utilizing an atmospheric leach followed by a CCD train

There is an adjacent dedicated port facility where concentrates are received, with final products dispatched by road and rail. Port Pirie is an integrated multimetals recovery plant with the flexibility to process a wide range of lead rich concentrates and smelting industry byproducts.
Copper Process Flowsheet Example. The crushed ore will be processed by means of semiautogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate. The concentrate will be trucked via the existing road network in the area to a port facility for shipment to smelters.

The Auby smelter is a midscale electrolytic zinc smelter. It produces cathodes as finished products, rather than casting into ingots. Feedstock of both zinc concentrates and zinc secondaries is consumed at the plant using the RLE process to produce zinc cathode. Key facts. Products special high grade (SHG) zinc, sulphuric acid, indium metal

Konkola Copper Mines' (KCM) Nchanga smelter utilises a modern technology of direct to blister flash smelting process designed by Outotec, Finland. Slags from the direct to blister flash smelting unit are carbothermically reduced through a two stage electric slag cleaning
Figure 1. Flow sheet of the Directto Blister Process at Nchanga smelter Slag Chemistry One of the leading ideas in the design phase was to minimize the slag amount, which contributes to high copper recovery in the DBF and in the entire process. This could be .

Designing gold project flowsheets It has been said that gold was one of the first metals to be mined. As deposits with free, coarse gold were depleted and the volume of mining increased, process flowsheet design became more and more complicated.
