1 MINING PREAMBLE This syllabus is designed to evaluate the candidates' knowledge of the basic principles and practices in the mining industry with a view to developing their interest in the business of mining.
In recent years, the industry has adjusted its mining methods from those needed for highgrade underground deposits to those for lowgrade, openpit, polymetallic deposits. Meanwhile, large freemilling gold operations are seeing their deposits become more refractory.
In nature, there are more than 20 mineral forms of gold. It is difficult to choose a method for separating of gold. Minerallurgy can significantly reduce the cost of reagents for hydrometallurgy and reduce the volume of leached ore.

Mineral Processing Golden Mile ore is of two main types: weathered oxide ore from near the surface which is freemilling with the gold easy to extract, and sulphide ore in deeper ore bodies where the majority of the gold is locked as inclusions in tellurides and pyrites and is difficult to extract.
Hard rock mining, placer mining, byproduct mining and gold ore processing are some methods of gold mining. Each method has its unique process of accessing, extracting and processing gold.
