The use of thiourea, (CS (NH2)2 as a complexing/extracting agent for gold and other precious metals has shown promise for implementation in the mining/metals industry. Laboratory testing of this reagent has indicated that a thiourea process for gold extraction has several advantages over conventional processing techniques.

WhatsApp: +86 18838072829Mining Jun 16, 2017 Beginners guide to thickeners Thickening is a process where a slurry or solidliquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes).
WhatsApp: +86 18838072829The ability to create a high thickener underflow density can allow for less stages in the circuit, reducing costs. At FLSmidth, we have developed gamechanging technology that creates a high thickener underflow density, protects thickeners as an asset and maximises soluble metal recovery. The following technology gets your team these notable ...

The processed material "tailings" comes from the "tail" end of a mining mill and comprise fine particles mixed with water forming a slurry. Mining companies will store this waste in dams or ponds.
WhatsApp: +86 18838072829The operation of dewatering is performed in two stages. First, the bulk of the water is removed in a thickener, from which the concentrate is discharged as a thick pulp ; as a rule the underflow contains 55 to 65% of solids, while 70 to 80% of the original water is recovered in the overflow as a clear liquid. The thickened pulp is then sent to ...
WhatsApp: +86 18838072829The core of thickening process control is to adjust the underflow ore drawing speed in time according to different working conditions. When flocculant is added, it is necessary to adjust the amount of flocculant in time to obtain the best sedimentation velocity, so that the underflow ore discharging speed and ore discharging concentration are in the best matching interval.
