The role of gravity concentration in modern processing

Next to hand picking, gravity concentration is the oldest of all forms of mineral processing. While, in the twentieth century gravity concentration has been partially replaced by other processes, notably flotation and magnetic separation, they have not made it obsolete.

Gravity Concentration In Modern Mineral Processing

Abstract. A review is presented of the range and type of gravity separation processes available and employed in modern ore treatment plants. Recent trends in gravity plant design, equipment and practices are identified to maximize productivity, improve metallurgical performance, minimize capital and operating costs and/or permit the profitable treatment of lower grade and more complex ores.

VI. GRAVITY CONCENTRATION

2012-8-10  VI. GRAVITY CONCENTRATION Gravity concentration process that exploits the differences in densities of minerals to bring about a separation is the oldest beneficiation method known to mankind. Although with the advent of froth flotation, the relative importance of gravity concentration has declined in twentieth century, on an

Gravity Concentration Methods SpringerLink

Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a
