In order to increase the recovery of PGMs by flotation, it is necessary to optimise the liberation of the key minerals in which the platinum group elements (PGEs) are contained which include sulphides, arsenides, tellurides, and ferroalloys among others, while at the same time ensuring the optimal depression of gangue minerals. In order to …
Refining platinum ore is a costly and laborious process. It can take from eight weeks to six months to process a batch of ore, and it can take up to 12 tons (11 tonnes) of ore to produce a single troy ounce of platinum.

Description. Platinum (element #78, symbol Pt) is a dense, silvery-gray metal. The platinum group of elements consists of metals with similar physical properties as platinum and these elements are among the rarest in the Earth's crust. They have high melting points, are dense or heavy and are non-reactive with other elements.

Once the platinum-bearing ore is obtained, it undergoes a series of processes to extract the platinum minerals. This usually involves crushing and milling the ore to reduce its size and liberate the platinum particles. The next step is often flotation, where chemicals are used to separate the platinum minerals from other unwanted …

The bauxite ore contains aluminum trihydrate (Al (OH) 3 ). Alumina refining produces alumina (Al 2 O 3) from the bauxite ore, by exploiting the reversible reaction of the Bayer process 1–3 : The reaction is firstly driven in the sodium aluminate (NaAlO 2) direction by the addition of caustic soda (NaOH) to bauxite.

Relatively deep deposits, or those with elongated or irregular shapes are typically mined from underground with deep vertical shafts, declines (sloped tunnels) and levels (horizontal tunnels) (Figures 8.2.1 and 8.2.2). In this way it is possible to focus the mining on the orebody itself. In some cases, the near-surface part of an orebody is ...
Once the ore is on the surface, the process of getting the mineral you want out of the rock can start. Once the mineral is separated from the rest of the rock, the mineral needs to be cleaned so that it can be used. This process can be represented by the following flowchart diagram: In this chapter we will look at each of the steps in more detail.
