Reasonably priced rock crushers can also be bought that will make short work of any specimens that you want to break up. 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.
Weathering is the process that changes solid rock into sediments. Geologists use the word sediment to describe all different sizes of rock particles. Sediment includes really large pieces of rock, like boulders or gravel, but it also includes sand and much smaller particles, called silt and clay.
The first step in processing the ore removed from the mine is to break the large rocks of ore into smaller pieces. This is accomplished by a variety of subsequent processing steps. ... The next step in the process flow is smelting for sulfide ore concentrate and solvent extraction for oxide ore .

Stages of Deformation. When a rock is subjected to increasing stress it passes through 3 successive stages of deformation. Elastic Deformation wherein the strain is reversible. Ductile ... The discovery of this process and its consequences involved measurements of gravity. Gravity is measured with a device known as a gravimeter.
Soil and waste rock is removed using conventional earth moving processes to access the ore. The walls of the pit are mined in a series of benches to prevent them from collapsing. To mine each bench, holes are drilled into the rock and loaded with explosives, which are detonated to break up the rock.
