What are the different types of mining and how do they differ?

A rarely used process of mining material, In-Situ or solution mining is the process of pumping a solution into the ore body, which dissolves the ore and is then extracted by a second pump. This method is used most in mining uranium deposits, with the Beverey Uranium Mine in South Australia being the nations first operating In-Situ Uranium Mine.

12-12-2018 · Most underground mining methods have prohibitively high operating costs, which only allow high grade deposits to be mined. Block caving has a high production rate, which means high capital costs at the start of the project but relatively low operating costs. If there is enough ore, initial capital will be recouped over the life of the deposit.
