Conversion of these ores into metals requires oxidation/reduction reactions. That's not always the case. Some early forays into metallurgy involved native gold native meaning the metal is found in its elemental state in nature. Gold is relatively soft. It could be easily worked and shaped by heating it. Occasionally, native silver and copper can also be found. Problem RO6.1.

Copper ore was dressed somewhat differently than tin and was usually sorted and crushed by hand. Copper dressing relied extensively on manual labour throughout the 18th and 19th centuries, though mechanisation did play a part. Copper crushers Cornish rolls were introduced in the early 19th century and low grade or otherwise difficult ores were also
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. The most abundant ores are chalcopyrite and bornite,
called ore preparation, milling, and ore dressing or ore beneficiation. Ore dressing is a process of mechanically separating the grains of ore minerals from the gangue minerals, to produce a concentrate enriched portion containing most of the ore minerals and a tailing discard containing the bulk of the gangue minerals. Mineral dressing Since most ore minerals are
In the ore dressing plant, the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials, or gangue. In cases where the next step is leaching most frequently in the case of oxide ores, complete liberation of the copper minerals is not always necessary the ore needs to be

Ore oxidation Grinding chemistry abstract The influence of grinding chemistry on the flotation behaviour of sulphides minerals has been widely studied. However, its influence on partially oxidised sulphide ores is not well documented. Various oxidation events can affect a sulphide ore, either during in situ weathering of an ore body or during the different extraction and processing stages

Porphyry ore deposits, Earths most important resources of copper, molybdenum, and rhenium, are strongly associated with felsic magmas showing signs of high pressure differentiation and are usually found in places with thickened crust 45 kilometers. This pattern is well known, but unexplained, and remains an outstanding problem in our understanding of porphyry ore
Dissolution of copper and iron from malachite ore and The present work describes an investigation of a chemical process for the recovery of copper and iron from malachite ore.
