Domestic mining for chromite was restricted to a few locations in the United States, including Montana, California, and Oregon, and mining the mineral was only economically feasible during times of political conflict. During wartime, the United States government supported domestic production with price supports and strategic stockpiling programs.
pertain to the ore deposit being mined. Mining is never properly done in isolation,nor is it an entity in itself. It is preceded by geologic investigations that locate the deposit and economic analyses that prove it financially feasible.

Once exposed, the ore in the pit is broken up by blasting. A single blast can break approx. 3,000 tonnes of ore. Once the ore is broken, excavators load the ore into haul trucks and transport it to a primary ore crusher where the diamond extracting process begins. The Kimberley Big Hole is an example of open-pit mining.

Prior to the development of advanced technology mining equipment, freeing manganese from open pit rock beds required a lot more manpower and time. But compact mining equipment and its advanced technology allows manganese miners to produce far more of the valuable ore than was possible even a few decades ago.
MINING AND PROCESSING: Iron ore mining can be broadly divided into two categories namely 1) manual mining which is employed in small mines and 2) mechanized mining is suitable for large iron ore mines. Manual mining method is normally limited to float ores and small mines. Mining of reef ore is also being done manually on a small scale.
