I have been given a project on optimization of copper concentrate grade so as to improve copper and gold recovery. I need help on the main factors which I have to consider in my project. The targeted copper concentrate grade at the plant is 18 20%Cu, but currently the target is not achieved. The p
Copper concentrates are produced by the beneficiation, or upgrading, of copper ore. A typical copper ore would be 0.7% to 2% copper, a typical copper concentrate would grade around 25% to 35% copper. Copper concentrates are either smelted and refined in house, or sold to custom smelters.
Feb 09, 20170183;32;While gold concentrates sounds like one of golds chemically modified derivatives, it is in fact, natural. Better known as pay dirt, gold concentrates are sourced in two different ways. The first is through gold panning . When panning for gold, the objective is to separate the ...
The value of the free copper, gold and silver in a copper concentrates for a copper smelter is depending on the recovery rate, LME copper price and LMBA gold and silver price. In this example the recovery rate for a copper smelter is 98.0%. The value of free gold and silver is normally greater than the value of the free metal for copper.
Jan 01, 20160183;32;The conventional treatment of coppergold concentrates does have some compelling reasons to seek an alternative hydrometallurgical process for recovery of concentrate values. These include the following: 1. Capital Cost. The capital cost of smelter and refinery complexes is very high. The unit cost will vary according to scale and location.Cited by: 1
The occurrence of fluorine in the copper/gold concentrates produced by Ok Tedi Mining has provided a series of challenges to metallurgists since 1988. Although fluorine is distributed throughout the gangue minerals contained within Ok Tedi ores, its presence in talc and phlogopite has proven to be the predominate sources of fluorine...
May 01, 20170183;32;The gold copper concentrate prior to 50 times silica flour dilution has 3.75% Cu distributed amongst a range of reactive copper minerals, such as chalcocite, cuprite and native copper. The gold copper oxides ore contains 12.9 ppm Au and 0.04% copper. The gold copper sulfides ore mainly contains chalcopyrite as a copper mineral and it contains ...Cited by: 25
Gold sales account for 95% of total revenues, with 70% coming from dor233; sales and 25% coming from gold contained within the concentrate. The remaining 5% of revenues is from copper in the concentrate and a very small amount of silver. On this basis,
