We are now in a very competitive position to supply flocculants used in the mining industry. Florrea F300 series flocculants is equivalents and cost effective. Large quantities of water are used in the mining industry in order to separate valuable ore from its gangue and, at some stage in the process, it is necessary to separate the solids from the liquid phase.

According to the literature reports from recent years, the flocculation mechanism in the presence of polysaccharide flocculants is considered to be due to the two main mechanisms described below: (a) charge neutralization; and (b) polymer bridging [5,6,30].These two ways depend on the adsorption of polymer on particle surfaces as a …

The gold is particulate within arsenopyrite grains. The RGO ore is a complex refractory gold ore. Whilst flotation and concentrate roasting, pressure oxidation (POX), and bacterial leaching (BIOX) were all studied the environmental regulators would not agree to chemically changing the arsenopyrite containing the gold.

The use of natural and synthetic polymeric flocculants can be used to generate larger, more stable flocs and may reduce treatment times. This is achieved by bringing dispersed particles together, increasing the effective particle size. Flocculants can be used alone, or in combination with coagulants.
