Minerals

Every mining operation is followed by a beneficiation process aimed at delivering quality materials to the transformation industry. Mainly, in order to separate valuable minerals from gangue in mineral processing, the crushing and grinding of extracted ore are crucial operations for the following separation steps. Comminution is the most energy-consuming operation in mining, and the quality of

Comminution is usually the first stage in mineral processing plants. Normally the comminution circuit includes several stages starting with crushing and followed by grinding (Figure 1). Primary crushing is often done close to the mining area, e.g. underground or in the pit. Depending on the ore and process types there can be several

CONTROL OF CRUSHING CIRCUITS WITH VARIABLE SPEED

Jan 01, 20051. INTRODUCTION After extraction from the ground, minerals must be prepared for direct use or further processing. The first step in the gradual reduction of the hard mineral to fine powder or dust is carried out by a crushing circuit, which is energy demanding and its smooth operation can represent a big increase in the plant throughput.
