How Are Diamonds Mined And Extracted From the Ground
To make mining efficient and effective, the raw rock and soil are typically not examined on site. Instead, they are transported to special plants where the ore is processed and the rough diamonds are extracted. Depending on how rich the ore is, a few hundred tons of ore might be sieved just to produce a single carat of gem quality rough diamonds.
Mar 14, 20140183;32;Mining of Iron Ores. Iron ore is a type of mineral and rock from which metallic iron is extracted economically. This ore is normally rich in iron oxides and vary in color from dark grey, bright yellow and deep purple to rusty red.

Open pit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of open pit mining. The removal of this material is known as stripping. The stripping pit limits must be extended beyond the limits of the ore pit to provide a bench, and the pit
Cut off grade determination for the maximum value of a
g is the average grade of the ore above cut off. In the limiting cases the following formulae apply for mining for processing and for marketing Note the last two terms for the processing and marketing equations are identical in form and in each case the cut off grade will fall as F declines because the remaining life of the mine is reduced.

The U.S. mining industry consists of the search for, extraction, beneficiation, and processing of naturally occurring solid minerals from the earth. These mined minerals include coal, metals such as iron, copper, or zinc, and industrial minerals such as potash, limestone, and other crushed rocks. Oil and natural gas extraction (NAICS code 211) is not included in this industry.
