Gold Refining Methods iron ore mining

Sep 15, 2011The Wohlwill and Miller processes are the two main methods used to refine gold today. When purity standards are lower, the Miller process is generally chosen. Other processes are available, such as parting and inquartation, cuppelation, or the dissolution of gold in aegis regia. These processes are better when smaller amounts of gold need to be refined.

How gold is made history, used, parts, procedure

Mining. 1 In lode or vein deposits, the gold is mixed with another mineral, often quartz, in a vein that has filled a split in the surrounding rocks. Gold is obtained from lode deposits by drilling, blasting, or shoveling the surrounding rock. Lode deposits often run deep underground.

Mineral processing

Mineral processing

Mineral processing. Mineral processing can involve four general types of unit operation comminution particle size reduction; sizing separation of particle sizes by screening or classification; concentration by taking advantage of physical and surface chemical properties; and dewatering solid/liquid separation.

How Are Diamonds Mined And Extracted From the Ground

Because marine deposits are distributed over large areas unevenly, mining companies utilize different methods to mine them. Some of these methods include shallow water mining, deep sea operations involving high tech equipment and simple alluvial mining. Like open pit mining, the ore materials are usually transported offsite for further processing.

Surface mining (open pit mining) This type of mining takes place from the surface of the Earth. In open pit mining, the topsoil is removed first and placed on the side of a trench. Then the surface layers of rock are removed to expose the deeper, valuable mineral layers. The valuable rocks are then blasted into smaller rocks using explosives.
