Copper SX EW Basic Principles and Detailed Plant Design
Copper SX/EW Basic Principles & Detailed Plant Design 51 ORGANIC SELECTIVITY • The only significant element extracted by oxime copper extractants is ferric iron. • Copper-iron ratio of 500-2500 (under ideal conditions) depending on the particular extractant. • Actual chemical transfer is affected by the Cu:Fe ratio in the aqueous feed ...
12.3 Primary Copper Smelting
steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. 12.3.2 Process Description2-4 Mining produces ores with less than 1 percent copper. Concentration is accomplished at the mine sites by crushing, grinding, and flotation purification, resulting in ore with 15 to 35 percent copper.

Mining Business Plan Mineral Processing amp Metallurgy
Apr 21, 2016 The following document outlines a mining business proposal to design and construct a free standing toll plant facility, known in this document as Peru Toll Treatment (PTT), in southern Peru to accommodate the needs of a growing quantity of small scale miners who produce up to 14 percent of the country’s annual gold production. The plan includes the basic design criteria on which the plant ...
Flowsheet considerations for copper cobalt projects
The basis of the plant design is the treatment of an oxide/secondary sulphide deposit treating a 4 per cent copper head grade and a 0.05 per cent cobalt head grade at a treatment rate of 2.5 million tons per annum. This will provide a feed tonnage of 100 000 tons and 1325 tons per annum of copper and cobalt respectively. The design basis of the ...
