The present study evaluates the iron ore slurry transferred from a beneficiation plant to the filtration unit in a long range pipeline. Iron ore slurry is received in buffer tanks and distributed to vacuum filter discs. Vacuum disk filters remove water from slurry to produce a filter cake with outcome moisture content ranging 10% to 11%.

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.

Types of Water Pollution from Mining There are four main types of mining impacts on water quality. 1. Acid Mine Drainage Acid Rock Drainage (ARD) is a natural process whereby sulphuric acid is produced when sulphides in rocks are exposed to air and water. Acid Mine Drainage (AMD) is essentially the same process, greatly magnified.
