Copper Mining and Processing Processing of Copper Ores

Copper Mining and Processing Processing of Copper Ores

Copper Mining and Processing Processing of Copper Ores Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes , which will ultimately be made into products for everyday use.

Soft annealing   Annealing/Normalising   Heat treatment

Soft annealing Annealing/Normalising Heat treatment

A high temperature heat treatment process performed around A1, the aim of which is to make a material as soft as possible. For copper and brass alloy the physical process is different and the soft annealing temperature is between 300C and 650C for copper alloys and between 425C and 650C for brass alloys.
