Difference Between Clarifier and Thickener

The dense Thickener solids are raked to the thickener's underflow cone and are removed via a slurry pump through the underflow pipe. Underflow slurry densities can vary based on the type of material being processed, size distribution of solids being settled, or other process factors but as a general rule, range from 35-50% solids by weight.

Concentrate Thickener Operation

Within the scope of a de-watering circuit are three categories of equipment. THICKENERS, FILTERS and the DRIERS. Each one is a stage in producing a dry final product. One of the good things about milling is that the names of most of the equipment reflect what function they perform. With thickener's they thicken! The feed to them has low density.

Thickener Operating pH and Lime for Flocculation & Improved Settling

The thickener could be "sliming" and will produce a dirty overflow combined with a low density underflow. If this is a problem, a reagent called a FLOCCULANT is added to the thickener feed. A flocculent causes the slimes -to form into small masses of mineral. This will make the thickener load settle.

Counter Current Decantation

The recovery of dissolved gold from slime pulp in the cyanide process was first accomplished by intermittent decantation. This simple process consists in mixing with the pulp containing the values in solution, a solution of lower gold content, settling the mixture in a tank and decanting the clear supernatant fluid.
