The Consep Acacia Reactor is a complete intense leaching plant that maximises the recovery of gold from gravity concentrates. Often used downstream from FL Knelson Concentrators, the Acacia produces the optimum solid-liquid interaction for maximised gold leaching kinetics by using an up flow fluidised reactor as opposed to complex mechanical agitation.
Gold processing, preparation of the ore for use in various products. Native gold is the most common mineral of gold, accounting for about 80 percent of the metal in the Earth's crust. It occasionally is found as nuggets as large as 12 millimetres (0.5 inch) in diameter, and on rare occasions ...

New mill liners provide major productivity benefits. We've just launched PulpMax TM Composite Mill Liners - high-performance liners that improve throughput, increase safety and provide additional uptime. PulpMax Composite Mill Liners work with all SAG and ball mills and are designed for all minerals processing applications.
Gravity concentration is used for processing coal fines downstream of a cyclone, following desliming and sizing screening. After gravity concentration, coal streams are fed into dewatering screens, and then a Siebtechnik centrifuges. Gold beneficiation. Gravity concentration spirals are optional in gold processing, used for carbon degritting.
The economic benefits of gravity recovery are application dependent, as shown in Table 19.2.For more than 95% of all applications, gravity recovery targets GRG to supplement cyanidation or flotation, thereby increasing overall gold recovery by 1–10% and reducing some of the costs associated with carbon stripping and regeneration.
The new gold recovery plant thus incorporates state-of-the-art technology, with a degree of automation that helps to minimize manpower and to reduce operating costs. The gold is milled in a two-stage process, first through a grind mill followed by a ball mill in closed circuit with a cyclone cluster.
