The hot leaching method of ore processing is based on the physicochemical properties of NaClKClH2O system. The main principle of this method is the different temperaturedepending degree of solubility of the mineral components – sylvite and halite: the high solubility of potassium chloride from ore by cycling solution at 115°C and the further crystallization of the valuable component on ...

The SART plant reduces consumption of our two most costly reagents (cyanide and metabisulfite) by 2030%, or approximately 10M/year. It also decreases the cyanide content of our tailings by about 5x and produces a saleable byproduct with revenues that more than offset the plant's operating costs ( OPEX vs revenue). 1
The five basic types of reagent used in froth flotation recovery include collectors, frothers, depressants, activators and modifiers. When designing the processing plant, the types and quantities of reagents used should be considered together with any depressing requirements to lessen environmental impacts in the tailings streams (Ritcey 1989).

Wash water consumption is approximately the same whether wateronly or air/water backwashing is employed. INLINE CLARIFICATION. Inline clarifiion is the removal of suspended solids through the addition of inline coagulant followed by rapid filtration. This process is also referred to as inline filtration, or contact filtration.
