Dewatering, Thickening and Filtering

Arthur Pinto Chaves

Dewatering, thickening and filtering processes are fundamental in ore treatment and applied in different stages to reduce the humidity of a mineral product.

Dewatering, thickening and filtering, second volume of collection Theory and practice of ore treatment, didactically approaches topics such as mechanical water outlet, thickening, filtering, auxiliary reagents and theoretical aspects of filtering and water outlet.

For this new edition, filled with illustration and solved exercises, a revision and a general update of the content was made.

By Arthur Pinto Chaves and collaborators, Dewatering, thickening and filtering is a valuable reference for scholars, students and professionals in the field of Mining and Metallurgy.
