Following some process modifications, a precious metals extraction plant encountered filtration problems at the hydrometallurgy pretreatment sector. This step rendered chemical species that made the next step - filtrate clarification on a filter-press, almost impossible. Moreover, the species also caused more filtration problems at the subsequent gold retrieval step.
STS Canada was assigned a design engineering to optimize the filter's performances that ensure the removal of the undesired species.
Submit a filtration method that would provide the means to clarify the filtrate from the belt filter, down to a concentration lower than 10 ppm in suspended particulate matter. The proposal would also have to use the plate filter on site.
Laboratory testing made it possible to:
Ore processing - Hydrometallurgy
Liquid filtration optimization
Sector commissioning and support
