Iron oxide copper gold ore deposits
These ore bodies range from around 10 million to >4,000 million tonnes of contained ore, and have a grade of between 0.2% and 5% copper, with gold contents ranging from 0.1 to 1.41 grams per tonne. These ore bodies tend to express as cone-like, blanket-like breccia sheets within granitic margins, or as long ribbon-like breccia or massive iron oxide deposits within faults or shears.

The principal gold minerals that affect the processing of gold ores are native gold, electrum, Au-Ag tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important. The main causes of refractory gold ores are submicroscopic gold, the Au-Ag tellurides, and very fine-grained gold (

Here Is The Correct Way To Effectively Recognize Gold Ore
Gold is heavy and highly malleable. Gold will not change color, crumble, or tarnish, and is unaffected by most solvents. Gold is commonly alloyed with silver and other metals. The ore may, therefore, contain sulfides like arsenic, copper, iron, and silver. Gold ore does not usually have any shiny gold on the surface. Spotting it with the

Copper Mining and Processing: Processing Copper Ores
In addition to processing copper ores, new and old copper scrap or copper alloys can be melted, re-purified, and recycled into new components. It is estimated that such recycling supplies 50% of copper used in the copper industry (Scott, 2011). In 2010, 770,000 metric tons of copper were recycled, at an estimated value of nearly six billion dollars (Papp, 2010).

For example, a copper ore grade of 1% means that in 100 tons of the ore, we have 1 ton of copper. If the copper ore contains 40 tons of calcite gangue, we can also say 40% of calcite in the ore. A gold deposit with a grade equal to 5 g/t (gram per ton) means that in one ton of the ore, we have 5 grams of gold.
