How to Remove Arsenic, Antimony Bismuth from Copper

Feb 06, 2017  The ores of copper are usually associated with minerals containing arsenic, antimony and bismuth.Whatever the means adopted for extracting the copper, these metals are usually found, to a greater or less extent, in the product. There is, however, usually some elimination in the various metallurgical operations to which the ores are subjected, and some attempt is made here to

But the cold strip works up to a certain limit that should have been detected with proper mineralogical characterization. If the amount of copper is such that the ore really corresponds to "low grade copper with traces of gold", then a copper removal step employing for instance the SART process might be mandatory, in addition to the cold strip.

In addition, the process can be used to extract copper in situ. That is, without removing the material from the waste pile or from the ground. The net result of the use of this process is that copper can be produced from sources that in the past would have gone untouched, thus reducing the reliance on conventional ore bodies.

25.2 Extracting ores Mining of mineral resources Siyavula

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.
