Diamond Beneficiation in Botswana
The beneficiation of diamonds is a direct result of the conditions required to be a DTCB sightholder . One of the criteria is indeed that local processing should take place. Simply put, no processing, no access to rough diamonds. This policy required rough diamond traders to move down the value chain if they wanted access to rough diamonds.

What is iron ore beneficiation?
Iron ore is an important raw material for steel production enterprises. In most cases, iron ore with a grade of less than 50% requires ore beneficiation before smelting and utilization. Natural ore (iron ore) is gradually selected for iron through procedures such as crushing, grinding, magnetic separation, flotation, and gravity separation.
