Common copper ore concentrate equipment of copper processing plant is a traditional thickener, efficient deep cone thickener, inclined plate thickener; common filter used in a copper mining process plant are disc vacuum filter and a ceramic filter.
#0183;#32;In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH, after which the pH is reduced to with SO 2 (200 g/t) and the copper sulphide floated. Liu and Laskowski (1989) obtained selective flotation of chalcopyrite from galena using lime and dextrin (a watersoluble carbohydrate with chemical formula (C 6 H 10 O 5 )n) as depressants, at pH 11 to 12.

Difference Between Sag Mill vs Ball Mill mech4study
Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is
When operational, the equipment will process a total of 84 Mt of ore per annum. The order is valued at approximately DKK 1,700 million and will be booked in the first quarter of 2020.

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Control of SemiAutogenous Grinding(SAG) mill weight is an example of an important process that exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell,, van der Westhuizen,, amp; Mainza, 2009).
Copper extraction refers to the methods used to obtain copper from its conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).
The crushed ore is transferred to a semiautogenous (SAG) mill or ball mill where the ore is about 20 to 55 percent solids is produced (Singh, 2010; International Mining, 2011) (see fig. 2). The mill operates in a closed circuit approximately to 3 t of water are required to process 1 t of copper porphyry ore that contains roughly
