ISR Mining Uranium One

Conventional mining involves extracting ore from the ground and processing it to extract the target minerals. ISR (in situ leaching, also known as in situ recovery (ISR) or solution mining) involves using liquids (commonly referred to as "leaching liquors" or "lixivants"), which are pumped through the orebody while it is in the ground to recover the minerals from the ore by leaching.

Diamond Recovery Methods Latest News

Mar 30, 2016 · Some alluvial mines can completely skip the crushing stage if the diamonds are found in sand, earth or fine gravels. Crushing is a multistage process of breaking the rocks into ever smaller pieces and recirculating larger pieces until everything is the right size to enter the processing plant.

How Are Diamonds Processed? Our Everyday Life

How Are Diamonds Processed? Before a diamond is even processed, it must be mined first. The mineral is recovered from ore through a process known as comminution and liberation. Comminution is the breakage of larger ore into smaller particles. The liberation is the process of removing the incorporated diamond from the ore.
