Stages in Tin Mining

Tin or lead is a silvery-white metal, with a low hardness, a specific gravity of 7.3 g / cm3, and has high thermal conductivity and electrical properties. Under normal circumstances (13 – 1600C), this metal is shiny and easily shaped. There are 2 kinds of tin namely Sn (stnnum) or tin and Pb or lead. That is why usually distributors of this kind of strategic metals, for example, the smh ag, will usually have both of the types, lead, and tin.

Just like many other metals, tin and lead also need to be mined. There are several stages in tin or lead mining. So, they will be discussed below:

1. Assessment or Exploration phase
The purpose of this step is to find out how much of this metal stock, some of its components include initial mapping or survey, drilling well or small drill means taking metal samples with ground drill technique and performing analysis in the laboratory. So the geological map mapping is crucial.

2. Mine Operation Phase
This phase includes two stages of offshore and onshore pensions. For offshore, typically the company operates using a fleet of crack ships, bucket (bowl) dredges have a size of 7cuft to 20 cuft, used at a depth of 15 to 50 meters below sea level, dredger is capable of digging more than 3 and a half million cubic meters of each material month.

3. Phase increase of metal ore content or processing
This process is done to get the final product of quality metal with low impurity content and high sn or pb

4. Phase melting
This process merges the ore into tin, and it must be purified first with a crystallizer purifier

5. The marketing distribution stage
This process involves the activities of selling or distributing refined tin into or outside the country where the lead and tin is obtained.
