Recovery of the fraction - 20 mesh (0.84 mm) in rejecting of the pulp preparation plant of Moanickel Company S.A. Pedro Sotto Alba

Abstract

This work shows the results reached in the environmental impac t reduction caused by the technological stream called Slurry  Preparation Plant  Reject that is obtained from the limonitic mineral extracted from  the lateritic orebody in  Moa, Holguin, Cuba, after  the installation of the Reject Circuit for the treatment of that stream. With the installation of this Reject Circuit, for which its environmental license was requested  and  approved, the Recovery Efficiency of useful ore particles of -20mesh(0,84 mm) increases from a value of 85,27 % obtained in the period before the circuit  installation to values  of 97,38% obtained after the circuit installation. The Reject Circuit installation eliminated completely the reject stream spillage to Cabañas River and allowed also to reuse  the cleanreject material in the mining roads construction, with which
agreat  part of that extracted from the environment is returned to it , thus reducing practically to cero the environmental impact caused prior to  it s installation.
