Current situation and prospects for the clean utilization of gold
Li et al. (2021) studied the influence of the dosage and particle size of gold tailings on the density and mechanical properties of ordinary C30 concrete, and they fitted the relationship equations between the content of gold tailings and the density and compressive strength of concrete. These equations shows that the compressive strength …

We attempted to use HCl-NaCl slurry electrolysis to recover gold from CPU slots (Li et al., 2019). Almost all the gold was recovered. Although slurry electrolysis is proven to be an efficient technique for recovering valuable metals, its current efficiency is generally low during the recovery process (Liu et al., 2022b, Yang et al., 2018).

Beginners guide to thickeners
Thickening is a process where a slurry or solid-liquid mixture is separated to a dense slurry containing most of the solids and an overflow of essentially clear water (or liquor in leaching processes). The driving force for the separation is gravitational, where the differences in phase densities drive the separation of the solids and liquid.

Ultimo Density Meter
Process plants no longer need to rely on nuclear densitometers or costly Coriolis devices to measure the density of abrasive, caustic, or corrosive process material. The Ultimo Density Meter measures more accurately, with unmatched uptime and without needing periodic recalibrations or maintenance, whatever the content material.

How Slurry Gold Works
SLURRY GOLD achieves enhanced nutrient retention during storage by both creating an optimal environment to support healthy microbial activity, and by adding specific bacteria to target certain processes that optimise the transfer of nitrogen into a stable nitrate. As crust formation is minimised, this allows light and air to access the slurry.

Evaporation losses are high. Loss of water entering the pond to evaporation is in the range of 33–50%. Many gold mines in arid climates tend to be at the 50% level or higher. • Deposited slurry will segregate, with the coarse material collecting near the discharge outlet and the fines flowing to the dam before depositing. •

Cyanide Leaching Chemistry & Gold Cyanidation
Coarse gold is usually removed ahead of cyanidation by gold traps, blankets or other standard methods and is treated separately. Otherwise, the dissolution process would be prolonged unduly due to the concentration of coarse gold in the grinding circuit, and the danger of high gold cyanidation residues would always be present.
