How much metal does the ore contain? « World

One example is copper. Copper ore does not contain pure copper, but either a copper-sulphur-iron compound (chalcopyrite) or a copper-sulphur compound (chalcocite). The metal must first be separated from such minerals by means of multi-step metallurgic processes. In many cases these processes are so complicated that they account for up to 30 per ...

Mineral Deposit Value - How to Calculate the

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).

2 天前  A gold-iron phase diagram derived from the data of Seigle (1956) is shown in figure 5, and illustrates a number of features important to removing iron from gold. Firstly, no more than 27% Fe can be tolerated when the gold melts to avoid inclusion of refractory high-iron solid phase components in the bar.

How to Calculate Grade and Recovery with Examples ...

2021-3-2  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.

What is Gold Ore worth? High Grade Mining Ore

This would generally be considered a very high-grade ore, worth mining in most cases. Using this hypothetical value of 1 ozt./ton, each pound of ore would contain approximately 0.0005 ounces of gold. Now let’s assume that gold is valued at $1500 per ounce. That would make the gold in a one pound ore sample worth approximately 75 cents, and ...
