The extraction of silver in the mines occurs in the following way: First, it is prepared to dynamite the area, be it in front or to Sky. The dynamite is connected to a wick whose name is "thermalite". Said wick has two capsules or terminals; one of them allows the fuse to be lit, while the other detonates the explosive.
After the explosion, the metal is loaded in the pneumatic shovels and transferred to the deposit that receives the name of piggy banks.
The use of breakers
Later, in the deposit, the silver is placed in primary machines called breakers. The function of the breakers is precisely to reduce the size of the stones where they are then passed through the sieves (which are like domestic sieves). So then they go on to a second bankruptcy. At this time a sampling is done to determine the purity of the silver. Once the silver has been reduced to the desired size, it is moved through belts to grinding.
Grinding
In milling, the silver enters some steel mills where it is converted into sludge, since it is constantly mixed with water for grinding.
The addition of cyanide
Cyanide is then added to this silver mud. This is carried out in continuous movement with some species of raking.
Floatation
The cyanidation process produces foam that is collected in the flotation.This process consists of container cells and impellers that rotate causing the silver particles to separate from the earth and ground stone. In this way the silver manages to float on the foam. Thus, the foam is released through lateral ducts and sent to the next area: the foundry.
Foundry
In the foundry, the collected foam is placed in canvas bags where they are compacted by means of a pressure process. Thanks to this pressure that is exerted, it is possible to divide the cyanide water, on the one hand, and the anode sludge, on the other, which allows the deposit in the sludge for their melting.
The oven
Once placed in the furnaces, the anodic sludge is smelted. This smelting is carried out after the use of diesel or petrolatum (which is a derivative of petroleum, but with a lower degree of purity than this).
Refinery
Once the silver anode sludge plates are obtained, they are deposited in vats and, by means of chemical and electrical processes, the plates disintegrate. In this way they become silver crystals that are called silver grit. Later, the silver granules are transported to the furnaces in order to melt said material.
As the final part, once the silver is melted, it is deposited on rotating plates that rotate horizontally around the furnace.
