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 direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Copper Ores. An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale.
Nov 01, 2019· Processing plants for porphyry copper ores are generally very large, processing up to 200,000 tpd of ore (JX Nippon, 2018)), and emphasis is put on throughput. Ores with low pyrite content (<2%) are generally considered easier to process (and the reagents scheme only includes copper collectors, pH regulator, and frother).

Less than two years later, these strategies have, broadly speaking, paid off. Operational efficiencies have increased and, as many countries demand more and more commodities (including coal, copper and iron ore) to underpin the expansion of their infrastructure, the mining industry is once again thriving with commodity prices rising.
1.1.5 Ore extraction After a mining company has removed overburden, extraction of the mineral ore begins using specialized heavy equipment and machinery, such as loaders, haulers, and dump trucks, which transport the ore to processing facilities using haul roads. This activity creates a unique set of environmental impacts, such as emissions of

2008). Application of times series to many data sets from mineral processing plants was shown to be a suitable method (Napier-Munn and Meyer, 1999; Meyer and Napier-Munn, 1999; Ganguli and Tingling, 2001) since the data structure is identical to the time series form. Many ore quality characteristic values in mineral processing

considerably from one mineral to another at operating mines—much less than 1% by weight for gold, more than 60% by weight for some iron-ore mines. Ore usually is transformed into concentrate at the mine site. Concentrate is an upgraded material. For example, copper ore often has a grade of about 1%.
Section(b)(3)(A)(ii) specifically exempts "solid waste from the extraction, beneficiation, and processing of ores and mineral, including phosphate rock and overburden from the mining of uranium ore."

The Mining Platform identifies mine type (above-ground, underground and solution) and mining method.
As you can see in the example above, the deposit does not have to be enormous in size (only 500 meters long by 100 meters wide) to contain a valuable deposit (approximately $6 billion worth of minerals). However, in order to be as realistic as possible about this valuation, you can not assume that the complete ore body contains the same grade (i.e. 2% copper and 1.5 gram per tonne gold).
