Several techniques are used to process the diamantiferous ore. The techniques used will not be the same between artisanal and industrial mining, however there are some common elements: Crushing, not too fine (rough diamond must not be crushed). Screening separates the sand from large elements. Washing disaggregates muds from ore.

The 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.
The mineralisation area of the 'Here's Your Chance' deposit covers around two square kilometres and is 55 metres thick. It comprises eight recognisable and discrete zinc and lead ore zones. The natural movement of the earth changes the orientation and angle of each zone over time, which complicates our mining process.
The development of more efficient processing techniques in the late1800s allowed the mining of lowergrade copper ores from huge openpit mines in the western United States. Today, the United States and Chile are the world's top two copper producing countries, followed by .
