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.
