Copper Nickel Pilot Plant Flotation. Pilot plant flotation tests for both the pit sample and the shaft sample were done in the Bureau's TCRC flotation process demonstration plant. Both samples were tested using flotation circuits that consisted of a rougher float followed by three cleaner floats, plus a scavenger float on the rougher tails.
The mine tailings dams in South Africa are currently viewed as a source of alternative supply of gold and other metals, especially uranium as well as a source of sulphuric acid. Recovery of other heavy metals from tailings dams is in the increase, for example silver, hence the need to evaluate heavy minerals in mine tailings dams.
Tailings consist of ground rock and process effluents that are generated in a mine processing plant. Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings.

In a sector bedevilled by protracted industrial action, and a lack of new discoveries and investment, as well as ever deeper and ever declining orebodies, gold tailings retreatment operations have demonstrated better resilience and attracted more investor interest than traditional operations, 71% of which were either marginal or lossmaking in 2018, according to Minerals Council South Africa.
Apr 04, 2013· Middling is the middle product in beneficiation process. Content of economic components in middling is generally between the concentrate and tailings. Middling is usually returned to early stage for processing in beneficiation flow, or separately treated.
PHASES OF A MINING PROJECT There are different phases of a mining project, beginning with mineral ore exploration and ending with the postclosure period. What follows are the typical phases of a proposed mining project. Each phase of mining is associated with different sets of environmental impacts. Exploration
