For a correct concentration of desired metal, it is necessary to maintain an alkaline solution containing ore, with a correct acidic pH of the water derived from said mineralogical processes.
The mineral deposits are distributed accordingly to the different geological processes in a non-uniform way, along the lines of geography and the Earths crust. The grade contained in ore determines the viability of the exploitation deposit. The required minimum grade depends on which metal it contains and how much you want to extract, meaning the lower limit shows how much more valuable the metal is.
The separation and concentration of the metal content in the ore, requires a complex process that can be summarised in three steps:
For the concentration, various techniques can be used:
Calcinor products perform a decisive role in the mentioned productive processes. Lime is used in the production of copper, molybdenum, zinc and lead. It is also used in the separation of gold, silver and nickel as well as in the refining of metals such as magnesium, calcium and mercury.
Calcium oxide, acts in the flotation process controlling the pH system as a precipitant. It is used mixed together with other agents such as: foams, activators, precipitants,
In this case acts as a pH regulator of the water generated in the process prior to its discharge into the river, allowing at the same time the separation of metals contained in this water for reuse.
