How Sedimentation Water Treatment Works and How to Make it …
Sedimentation is the separation of suspended solids from a liquid by gravity. As solids and particles fall out of liquid suspension and settle, they become sediment. This process, often referenced as settling, is regularly used in water and wastewater treatment. Suspended solids in a liquid can range from fine sand (>1,000 nm) to colloids (1 ...

How to Separate Gold from Sands?
Under the action of flowing water, gold ore fragments are brought into the river and further shredded during the handling process, slowly separating the gold out of the ore. Since gold is a large specific gravity mineral with a specific gravity of 19.32 g/cm3, fine gold will deposit at the corner of the river (slow flow rate), forming the ...
