Removing the goldbearing rock from the ground is just the first step. To isolate pure gold, mining companies use a complex extraction process. The first step in this process is breaking down large chunks of rock into smaller pieces. At a mill, large machines known as crushers reduce the ore to pieces no larger than road gravel.
Research the geological properties of a particular goldbearing area of interest. These properties include the rock formations, structure, fault lines and the primary mineral content of the area. Also, study the mineralization process of gold in general to determine which segment of a particular area may yield gold. (See Reference 1.)

Silver processing Silver processing The metal and its alloys: Even silver that has been fully workhardened, either by rolling or forging, gradually recrystallizes, even at room temperature. This greatly softens the metal, making it susceptible to scratching and marring. To maintain hardness, therefore, other metals are added to form alloys that are harder, stronger, and less prone to fatigue.
Sep 03, 2020· Therefore, gold prices tend to be much higher than silver prices because it is much harder to get. The reason supply is much larger for silver is because it is an easier metal to mine and it is often mined as a byproduct to other metals mining. The average occurrence of gold in igneous rock is parts per million.
