Jul 25, 2018· Block caving is an underground hard rock mining method that involves undermining an ore body, allowing it to progressively collapse under its own weight. It is the underground version of open pit mining. In block caving, a large section of rock is undercut, creating an artificial cavern that fills with its own rubble as it collapses.
Once the ore has been broken up into fine dust, testing for free gold content in hardrock ore can be done using some type of gravity method. A simple gold pan can be used to sample small amounts of crushed ore, or if a decent water supply is available then it can be run through many types of separation devices. Shaker tables are commonly used, and although quite expensive, …

Ore is natural rock or sediment that contains one or more valuable minerals, typically containing metals, that can be mined, treated and sold at a profit. Ore is extracted from the earth through mining and treated or refined, often via smelting, to extract the valuable metals or minerals. The grade of ore refers to the concentration of the desired material it contains.
