The simplest manufacturing process for producing silicon carbide is to combine silica sand and carbon in an Acheson graphite electric resistance furnace at a high temperature, between 1600°C (2910°F) and 2500°C (4530°F). Fine silicon particles can be converted to silicon carbide (SiC) by heating in the excess carbon from the organic material.

Silicon carbide develops a cylindrical ingot around the core, forming layers of ɑ-SiC, β-SiC, and an unreacted material on the outside. ɑ-SiC is the highest grade with a coarse crystalline structure, and β-SiC is the metallurgical grade. Based on the raw material quality, the SiC can be produced as either green or black.

Gold milling, which is also known as fine grinding, pulverising or comminution, is a grinding process that reduces materials into a powder or finer sized particles. Milling is used to recover the maximum amount of gold from the ore by finely grinding it so that gold particles can be removed through gravity separation and/or chemical extraction.
