Autogenous grinding is a process of grinding ore in a rotating cylinder, using large pieces of the same ore. Autogenous mills operate mechanically like ball mills; however, the media used for grinding differs. Simply put, in autogenous grinding, the media is also the material that is being ground, whereas in other milling methods steel or ...

The grinding circuit, represented i Figure 1, comprises a semi-autogenous (SAG) mill and a ball mill (BM). Both mills operate in close circuit with separate ydrocyclone clusters. Water is added independently to each mill as well as to each pump box for level control. The final product undergoes a gold leaching process.

Autogenous Mill. Autogenous mill is a type of grinding equipment that crushes material by mutual impact, grinding and peeling effect among material grains. In 1880, cylindrical grinding mill was invented. In 1899, it was used at a gold mine. Since then, it was discovered that autogenous grinding of ore is possible.

An autogenous weld is a type of weld in which the two pieces of metal being joined are fused together without the use of any filler material. This is achieved by heating the metal to its melting point and bringing the pieces together under pressure to create a bond. Autogenous welding is typically used when joining similar metals and can be ...
