B. Processing of Sulfide Ore Sulfide ores are generally processed using pyrometallurgy, the extraction and purification of metals by processes involving the application of heat. This process uses a series of physical steps and high temperatures to extract and purify copper from copper sulfide ores, in four basic steps 1) froth flotation, 2
As in any mineral processing operation the efficiency of the flotation separation is highly dependent on changes in feed characteristics all of which may influence product grade and recovery (Nashwa, 2007).
Optimization of circuits for pressure leaching of sulphide ores and concentrates The options for configuration of a circuit with two autoclaves are parallel, series, and series with interstage
CIRCUIT PROCESS FLOWSHEET DESCRIPTION: A Flash Unit sulphide Flotation Cell followed by a gravity concentration plant. This flowsheet shows the use of the Unit Flotation Cell, to extract/recover bas metal sulphides, in the ball mill classifier circuit in a plant where subsequent treatment consists of the usual gravity concentration methods.
Processing of the three ore types, namely leached ore, mixed float and sulphide, is through either an oxide circuit or a sulphide and transitional ore mixed float circuit. Treatment of the sulphide ore involves crushing, milling and flotation to produce copper in concentrate.
A New Paradigm in Sulphide Processing By classifying ﬂotation feed at a point where coarse recovery deteriorates, the existing ﬂotation circuit can be optimized to improve performance
The Phase II Sulphide Expansion is envisioned as a 3,000 to 3,500 tonne per day ("tpd") sulphide circuit to process zones of higher-grade sulphide and lower transition oxide resources starting in Year 3 of commercial production. Capital for this expansion is …
Copper-Lead-Zinc ores The Cu-Pb-Zn separation process is among the most challenging flotation separations primarily because the first step must entail bulk flotation of the two most readily floatable minerals with these two minerals separated in a differential flotation stage.
Sulphide Gold Recovery Pre-concentration of coarse 350 – 500 micron sulphide-associated gold ore, using the InLine Pressure Jig, is required to reject gangue from the high value material. The IPJ, a classic pre-concentration device, is effective in gangue rejection prior to further processing of valuable gold-bearing material.

2018-03-12· Copper extraction. Copper extraction refers to the methods used to obtaining copper from its ores. The conversion If the ore is primarily sulfide copper minerals (such as chalcopyrite), the ore is crushed and ground to liberate The first stage of any process within a metallurgical treatment circuit is accurate grinding or comminution ...
Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.
THE CESL GOLD PROCESS T. Robinson, K. Mayhew, D. Jones and K. Murray CESL Teck Resources Limited 12380 Horseshoe Way Richmond British Columbia, Canada V7A 4Z1 ABSTRACT The CESL Copper Process was developed as a hydrometallurgical alternative to smelting and refining for copper sulphide concentrates. As the majority of such concentrates contain appreciable gold and silver …
The operations at Suzdal are among the most technologically advanced within Nordgold, as the plant possesses the technology necessary to process refractory sulphide ore. The BIOX processing circuit at the mine was the first in Eurasia.
Introduction to Mineral Processing. Froth Flotation Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer. Sulfide and non-sulfide minerals as well as native ...
pyrometallurgical processing route of copper sulphides. Three copper sulphide leaching and refining processes are discussed: total pressure oxidation, ferric sulphate leaching and copper chloride leaching.
"A New Age Gold Plant Flowsheet for the Treatment of High Grade Ores" Crushing and grinding The first stage of the treatment process is the size reduction of the ore particles down to a size
Copper Mining and Extraction: Sulfide Ores. In an electric circuit, electron flow goes from negative to positive so the process transports electrons from the cathode to the anode.
R. Dunne, in Gold Ore Processing (Second Edition), 2016. 9 Flotation Circuits. Flotation circuit configuration on most gold mines can be divided into a number of categories, viz. open circuits with no cleaning at all, and open and closed circuits with single stage and two stages of cleaning.

Instead of relying on autoclaves or roasting to prepare a sulfide ore for traditional leaching, our vibratory grinder on our circuit allows our leach to make contact with the precious metal encapsulated in the sulfide so leaching can occur. With the aggressive nature of our leach allowing us to process most ores in an hour, our process allows us to contain the amount of sulfur that is released ...
