Sulphurnet is a provider of applications where the recovery of the valuable metals is required. Sulphurnet provides highly automated solutions for these demanding applications. The goal is to offer highly efficient filtration units to recover fines (high as well as very low concentrations) from the liquid. The aim of the technology is the recovery of the valuable minerals so these can be reprocessed.
In today’s demanding solid-liquid separation processes, it is crucial to achieving the best possible and most trouble-free filter operation. In order to improve the production yield and decrease the plant’s total cost of ownership. Sulphurnet Dutch Engineered Filtration Solutions offers a wide selection of proven filtration products, backed by an experienced staff of industry experts.
DEFS provides highly efficient Self Cleaning Candle filters for the purification of the cyanide solution prior to the zinc precipitation step. The high filtration efficiency improves the gold scavenger operation. The filter cake can be discharged as a wet slurry or a semi-dry filter cake. Prefabricated Skid mounted filter units make implementation faster, so ROI is shorter.
Concentration is a process where liquids’ solids content is increased. This involves the removal or recovery of additional liquid. Sulphurnet offers an economical solution for the clean-up of the thickener overflow. This overflow is contaminated with low concentrations of fine particulates, including metals and metal salts. These metals can be recovered and re-processed afterwards. Even very fine solids (1-2 micron) can be recovered. No flocculants or other reagents are required in this process. The filter media has very effective retention due to very fine pore size. This permits the recovery of very fine micron particles.
The filtration of copper electrolyte is required to remove electrolytic by-products and dirt which affect copper electrolysis. The process is performed/done/executed with precoat filtration in combination with activated carbon treatment Sulphurnet offer various executions for a high-efficiency filtration process as well as an effective activated carbon addition with efficient usage of the carbon.
