Slurry treatment from mineral and metallurgical processes – filtration of concentrates:

The filter presses used in these installations allow the slurry treatment for the recovery and recycling of economically important substances and waste disposal. we have been designed to maximize the performance of metal beneficiation (filtration of concentrates) and refining processes. Filtration has gained a thorough experience in the treatment of slurries produced in mines and in the metallurgical industry from the following processes:

• Flotation (filtration of concentrates):

Flotation is a process of solid-solid separation used to separate the gangue (waste mineral) from the pulp (desired mineral), exploiting the different surface properties of minerals. The several outlet currents from flotation, composed of concentrated minerals, are filtrated through filter presses.

• Hydrometallurgical:

lixiviation, is the process of separating one or more soluble elements from a solid substance using a solvent which can be chemical (acid), biological (bacterial strains) or organic (solvents containing carbon atoms)

purification through active carbons used in gold refining

• Pyrometallurgical:

it concerns the refining and working of metals through fusion from which oxides and sulphides are produced. filter presses are fundamentally used for the treatment of slurries obtained from fume-control processes.

• Electrolysis:

it concerns the decomposition reactions caused by continuous electric current in order to produce extremely pure metals and recover precious metals.
