Particle segregation associated with sub-sampling of flotation feed at a UG2 concentrator

Autor: V. Sibanda, N. Naicker

Publikováno v: Journal of the Southern African Institute of Mining and Metallurgy, Volume: 118, Issue: 1, Pages: 57-64, Published: JAN 2018

A concentrator treating an Upper Group 2 (UG2) reef ore has been historically under-accounting in terms of 4T (platinum, palladium, rhodium, and gold) content. The 4T content declared after sampling the flotation feed (or mill product) has always bee
