A theoretical design study for high capacity processing of a hard, fine grained silica rich magnetite ore, with several circuit options was carried out to assess the energy efficiency, operating cost and the project economics expressed through NPV. The CO2 emission was estimated and the carbon tax added in the operating cost.

primary crushing and belt conveying systems in mining projects successfully. INTRODUCTION It has been recognised in various studies that material haulage represents a major part of the costs in any mine operation. Considering the value chain from drilling and blasting to the stockpile of primary crushed material, haulage costs represent

low capital and operating costs. Crushing the ore to an allowable upper limit is the only size reduction step. A good rule of thumb is to avoid crushing if at all possible. If necessary to select the crushing system with a proven capability (Kappes, 1979). However, crushing the ore to an experimentally determined size and agglomerating
