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.

In 2017, Indonesia announced that it was in a position to allow nickel ore to be exported-only those with a nickel content of less than 1.7 per cent.
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
Over the years ORE Pty Ltd has pioneered a number of technological advances that have enabled the production of CRMs from ore deposits to an unparalleled level of homogeneity. OREAS® standards were ranked the most homogeneous among five CRM manufacturers in a study published in the December 2015 edition of the EXPLORE Newsletter for geochemists.
Sep 06, 2017· Whether high-grade or low-grade, nickel ores need to be processed after mining, in order to upgrade their nickel content from 1-4% Ni to 10-20%. Concentrating the nickel ores usually takes place close to the mine site, and involves chemical and physical processes to crush the ore and separate the nickel-bearing and gangue minerals.
Nickel processing, preparation of the metal for use in various products. Although it is best known for its use in coinage, nickel (Ni) has become much more important for its many industrial applications, which owe their importance to a unique combination of properties. Nickel has a relatively high

Copper extraction refers to the methods used to obtain copper from its ores.The 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.
Extract maximum value with minimum environmental impact when processing sulfide copper ores. We understand the intricate challenges and have the expertise and experience to design and optimize solutions to suit your specific ore type and – from complete concentrator plants to specific equipment.
The mineralogy of the Mesaba ore does not allow for effective production of separate copper and nickel concentrates, however, a low grade bulk concentrate may be produced with reasonable copper and nickel recoveries. Due to the capability of the CESL Process to handle bulk concentrates, Teck

Cobalt extraction refers to the techniques used to extract cobalt from its ores and other compound ores. Several methods exist for the separation of cobalt from copper and nickel.They depend on the concentration of cobalt and the exact composition of the used ore
In 2017, Kola MMC's total ore output amounted to 7.6 mt. Concentration facilities. One of its assets — the Zapolyarny Concentrator — produces briquetted copper-nickel concentrate. Briquettes are delivered to the Smelting Shop to produce converter matte.
The ore extracted from Raglan Mine is crushed, ground and processed on-site to produce a nickel-copper concentrate, which is then sent to the Sudbury Smelter for further processing. The concentrator treats approximately 1.3 million tonnes of ore yearly, resulting in more than 38,000 tonnes of nickel-in-concentrate annually.
