disseminated gold from the flotation concentrate resulted from processing of a refractory ore of one of Russian gold deposits. Concentrate description Gold grade of the head flotation concentrate was 29.6 gt. The concentrate size was 80 -80 um. Mineral composition of the concentrate comprises 17 of rock-forming minerals, 59 of pyrite and 24

Gold processing - Gold processing - Mining and concentrating The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade e.g., 3 to 10 parts per million that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...

Flotation is a selective process and can be used to achieve specific separations from complex ores such as lead-zinc, copper-zinc, etc. Advantagles of flotation concentrate machine Compared with common flotation machine, SF flotation machine has the following advantages 1. Increase concentrate grade of by 4-6. Add to Favorites.

This improves the amount of gold that can be recovered by further processing using equipment such as the InLine Leach Reactor. All gold concentrates produced by the InLine Pressure Jig can be intensively leached using the InLine Leach Reactor. For ore bodies less than 350 micron in size, a flotation flowsheet will be recommended.
