You can use the following equation: / weight of ore that used for leaching *Mn concentration in ore* leaching reagent volume )*100 ...
1. Calculate the Wall Area needed for the system by using Equation 1 Equation 1: Wall Area 2. Calculate the Area Flow of a section of the trench system using Equation 2. Equation 2: Area per Flow 3. Having these quantities you can now calculate the total Lineal Feet of trench space needed using Equation 3.
Decant off all clear water or solution. Then determine moisture content of pulp by weighing and drying. Calculating Thickener Area: Thickener area required is then calculated by applying above determined data in the following formula: A = 1.333 /R. A = Thickener area in square feet per ton of dry solids thickened in 24 hours.
The depth of each class of pulp would therefore be 2.23 ft., 2.57 ft., 2.87 ft., and 2.58 ft., or a total depth of 10.25 ft. To this depth must be added a foot for the loss due to the pitch of the drags in the thickener and 1.5 ft. for the depth of the feed, since the feed is thick and the volume will be proportionately low.
design calculations to determine the required thickener area, the most important design parameter, and ultimately the maximum steady state underflow concentration that is possible for a given solids throughput. In addition, the capital cost ofa thickener will be dependent on the calculated required settling area. Therefore,
