· 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 ...
contact usUnlevel buildings are the result of weak ground and/or subsidence. The appearance of internal or external wall cracks, inability to open and close windows and doors, cracked floors and more can all signal an unlevel building. Once a building becomes unlevel, it is important to fix it right away, or risk further damage and potential hazards.

contact usSettling ponds are large, manmade, relatively calm bodies of water used to store tailings. They allow the suspended solids in a slurry to separate from the liquid. Over time, the suspended solids settle to the bottom of the pond and accumulate there, leaving the water on top relatively free of contaminants so it can be pumped back to the ...
