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.
WhatsApp: +86 18838072829A gold mine was experiencing ongoing problems with froth formation on its preleach thickener. Feeds with entrained air are a challenge to the thickener flocculation process. Aerated thickener feed that makes its way into the body of the thickener tends to carry fine particles to the thickener surface to form froth.

WhatsApp: +86 18838072829Abstract Electronic waste is a dominant global issue with over 50 million tons generated annually. Still, as an amalgamation of precious and rare raw materials, electronic waste is a considerable economic resource with the most valuable components located on the printed circuit boards. Gold is widely used in electronics in numerous applications, although principally for contact points and ...
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 ...
