Hydrocyclones | McLanahan

Hydrocyclones are ideal for recovering down to 400 mesh (38µm) particles of 2.7 SG. This is typically done in the form of an Ultra Fines Recovery system comprised of a Sump, Pump, Cyclones and Dewatering Screen, which will have a discharge to waste nominally 90% passing 400 mesh (38µm) and a product discharging the screen in a drip-free, readily conveyable and stackable form.

Separation of Silica from Local Clay

sieving. Two different types of local clay were used for this purpose. Washing method was done to separate the clay particles. During washing an electrolyte was added to keep the clay particles in suspension. After separation chemical analysis of the separated clay was done. It revealed the presence of 58% silica in clay.

METHOD OF PRODUCING KAOLIN CLAY FROM ORE HAVING …

Kaolin clay is produced from ore having silica sand content in quantities that inhibit air separation of the silica sand from the kaolin clay by subjecting a slurry of the ore to agitation so that the silica sand acts to reduce or smear the kaolin clay to substantially natural particle size. This slurry is then subjected to rotation so that the ...
