Aug 14, 2021· Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was typically a byproduct of mining for other metals.
Laboratory and ore analysis . Quality samples equal quality results. Taking better ore samples will produce better-quality results. This sounds easier said than done, especially in mining applications where often consignments of many thousands of tons of ore product needs to be represented by final composite ore sample sizes that wouldn't fill a teaspoon.
Assaying Ores to determine gold content - Nevada Outback. Now this result does not take into account the purity of the free gold in the sample – and most natural gold does contain some silver and traces of base metals including copper.
Use RMB to take a sample from sand or gravel block. Rinse it few times in flowing water. There's a small chance it will drop a native ore nugget. Repeat the process until you have 10 copper nuggets. Smelting. Make sure you have at least 100 units of copper. Get Price
The amount of copper in the sample multiplied by 32,000 will be the copper in a ton of the ore. Should copper be suspected, roast the powdered ore and mix with an equal quantity of salt and candle grease or other fat; then cast into the fire, and the characteristic flame of copper first blue and then green will appear. This test is better made ...

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).
