Recovering highly viscous products from waste sites, mines and other deposits comprises adding alkaline products to viscosity-reducing additives during the process

摘要

Alkaline products are added to the additives in solid form to recover highly viscous products from waste sites, mines and other deposits. Recovering highly viscous products from waste sites, mines and other deposits comprises feeding the product to be mined to a reactor, diluting with viscosity-reducing additives to a pumpable consistency and conveying to a collecting vessel. Alkaline products are added to the additives in solid form.
