The concentration of zinc, lead and silver in the mineralized rock extracted from the Jayula and Tesorera pits in the San Cristóbal mine is very low; it is therefore necessary to have the material undergo a process designed to increase the content of these elements and thus obtain products with a commercial value.

Basic Mill Linings. Use rubber linings wherever possible due to lifetime, low weight, easy to install and noise dampening.; When application is getting tougher use steelcapped rubber, still easier to handle than steel.; When these both options are overruled (by temperature, feed size or chemicals) use steel.; Orebed is a lining with rubber covered permanent magnets used for special ...

The purpose of the concentrator is to reduce that percentage so that it can he economically he shipped to, and treated by, a smelter. To accomplish this the mineral must be liberated, prepared, separated and finally dried for shipping. The first stage, liberation, takes place after the ore is taken from the mine.

Concentrator. In the processing stage, the mined material is transformed into usable raw material. For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI ...

The concentrate contains only 53% of minus 325mesh material, 25% remaining on 200 mesh, and, being more granular than that obtained in the main flotation circuit, it gives better filtration. The total recovery remains much the same as before. Reagents are added in the ball mill feed box, and the pulp is maintained in the cell at about 58% solids.
