Question

each ore is a material but each material is not a ore explain it

Answer 1

YOUR ANSWER IS HERE:-

As a rule of thumb, at that time (early ‘90s) we considered a mineable grade to be 0.03 troy ounces of gold per ton of ore. This is only a rule of thumb because the metal produced from an ore is often a mixture of several metals. In the case of gold, it often contains copper, silver, and/or platinum. In addition to that, the price of gold always fluctuates, so the grade that can be mined at a profit is always changing, too.

“Mineable thickness” is also a slippery term. Deposits located at the surface can be surface mined, a process that is less expensive than underground mining. This allows the mining of thinner or less extensive deposits. A deposit that is mineable at the surface might not be mineable if it is located under 500 feet of overburden.

Geographic location is also important. If a deposit is located far from a railroad, transportation costs can sink the economics of the mine.

In the gold exploration project, we spent $2-million per year for about five years, but did not find a gold mine. The parent company shut us down when a recession hurt the company’s income.
