The stringent requirements of quality in mineral raw materials, such as kaolin, sand, silica or feldspar demanded by consumers of these materials necessitate a comprehensive design of the different stages that make up the treatment plant to ensure favourable results in the final product, even if the input raw material varies significantly.
This is why AMP ® defines the system or process plant study with great care in respect of the most important stages of the project, such as classification, thickening, filtration and dewatering, to ensure the viability of the project, resulting in systems and efficient plants for the production of:
- Kaolin, with products of extraordinary fineness for ceramic or paper industries.
- Siliceous sands, for use in filtration, foundry sands or sports fields.
- Frac Sands, complying with API RP 56 standard, whose quality requirements are well known to AMP, due to our extensive history and experience in other industries with similar quality requirements.
Pollution by heavy mineral sands
When pollution in the silica sands from heavy minerals (iron, titanium, chromite) reaches upper limits for the demands of glass manufacture, it is necessary to remove harmful particles to obtain a product with the required qualities. AMP specifies systems of magnetic separation or gravimetric concentration using concentrator spirals for the removal of polluting elements.
