Calculate Slurry Flow / Volume

calculate slurry flow volume

An example of how you can calculate the slurry flow/volume of a given SG, %Solids and Tonnage. EXAMPLE: 3,400 tons of dry solids is processed in 24 hours in water with a specific gravity of 1.0 and the concentration of solids by weight is 33% with the solids having a specific gravity of 3.7 then … Read more

Percent Solids to Specific Gravity Conversion of Slurry

calculate slurry SG

Here is the formula for specific gravity of a slurry, S is: S = specific gravity of slurry Si= specific gravity of liquid phase Ss= specific gravity of solids phase Cw = concentration of solids by weight Cv= concentration of solids by volume EXAMPLE: if the liquid has a specific gravity of 1.2 and the concentration … Read more

Filter Cake Moisture Analyzer | Scale to Measure Humidity

Filter Cake Moisture Analyzer

Part of your slurry dewatering system is the production of a filter cake. Obviously that cake must have as low a moisture as possible. A great tool you can give your operator to measure, determine and monitor that concentrate filter cake humidity and control their process variable is a moisture scale like this.  You just … Read more

How to Size a Cyclone | Hydrocyclone


How to Size a Cyclone or Hydrocyclone has a well establish step-by-step process for which Richard A. Arterburn was a pioneer.  Since this paper and its hydrocyclone sizing method is becoming hard to find, I uploaded it on here. Use the 911Metallurgist Online Cyclone Design Calculator. Hydrocyclone Design & Sizing Parameters – Calculations & Equations I … Read more

Hydroxamate Collectors

float oxide copper

Let me point you to two good papers on the flotation of mixed copper oxide and sulphide minerals with xanthate and hydroxamate collectors. A great detailed thesis called “An Investigation of Copper Recovery from a Sulphide-Oxide Ore with a Mixed Collector System” and one called “Flotation of mixed copper oxide and sulphide minerals with xanthate and … Read more
