Systems approach to grinding improvements at the Tilden concentrator

Mining Engineering, 2000, Vol. 52, No. 2, pp. 20-26

ABSTRACT:
Each of four sections in the Tilden concentrator consists of three primary autogenous mills in closed circuit with screens (in addition to coarse magnetic separation when processing magnetite ore) and six pebble mills in parallel. The pebble-milling circuits are fed by a sixway slurry distributor and are arranged in the standard closed-circuit arrangement shown in Fig. 1. Cyclone overflow, typically 80% passing 20 ?m, is upgraded by thickening-sizing, magnetic-drum separation (when applicable) and amine flotation to produce an iron-ore concentrate for further processing into pellets. Tilden typically processes approximately 20 million long tons (lt) of ore per year (1 lt = 1.016 t).
