Surface mining. Surface mining is exactly what the word says - digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining. An open pit coal mine.

Stages shown in time-sequential order are mining, crushing, grinding, ore separation and concentrate dewatering. From the mining phase two outputs are waste rock to the waste rock pile and waste water from both mining and the waste rock pile. Water and reagents are added at the grinding and ore separation stages.

The present contribution aims to point out that a new different type of waste such as the slag resulted from the gold-bearing electrolytic mud smelting may be capitalized using gravity separation on Gemini table and Knelson concentrator, respectively. Metal recoveries up to 90–92% Au and 46–60% Ag, respectively, were obtained on Gemini table.

Once the ore is retrieved, the diamond processing begins. The different phases in separating diamonds from ore include: Phase 1 – Crushing of the ore: The diamond-bearing ore is transported to a primary crusher, to crush the ore in to smaller particles, making it easier to handle (no bigger than 150mm). Phase 2 – Scrubbing and screening ...
