Hydrometallurgy Wikipedia

Insitu leaching is also called "solution mining." The process initially involves drilling of holes into the ore deposit. Explosives or hydraulic fracturing are used to create open pathways within the deposit for solution to penetrate into. Leaching solution is pumped into the deposit where it makes contact with the ore. The solution

Leachate Wikipedia

A leachate is any liquid that, in the course of passing through matter, extracts soluble or suspended solids, or any other component of the material through which it has passed. Leachate is a widely used term in the environmental sciences where it has the specific meaning of a liquid that has dissolved or entrained 

Easy Guide to Mining Waste Characterisation EESI Group

Waste characterisation needs to consider whether the waste will cause: Acid & metalliferous drainage (AMD) Saline and/or sodic drainage (i.e. neutral mine drainage) Leaching and mobilisation of metals and toxic compounds. Once exploration resulting in the discovery and definition of an ore body has been completed,

Landfill Leachate Treatment & Purifiion DAS

Landfill leachate is defined as all water that has been in contact with waste stored in a landfill. It is caught in the drainage system Properties and Challenges. Landfills generally contain a highly inhomogeneous mixture of materials, which include both a very high organic component as well as soluble mineral substances.

In Situ Leaching or Recovery Metallurgy & Mineral Processing News

At the Zarechnoye project in Kazakhstan, SRK developed a 3D geological model to define not only the boundaries, thickness and grade of the rollfront deposits, but also the variation in disequilibrium. This helped to explain some of the variability in leaching rates, which would then assist with trials to improve efficiencies.
