pentlandite crushing milling circuit:

Flotation of chalcopyrite, pentlandite, pyrrhotite ores ...

Nov 01, 1991  The flowsheet of the Frood-Stobie mill is shown in Fig. 1. The ore is crushed in a conventional three stage circuit with inter-stage screening. For many years 1NCO has prac- tised wet screening in the crushing circuit to remove the natural fines in the ore to facilitate the flow of rock through the crushers.
