The webinar will discuss two specialised models of CIL/CIP plants for assessing and optimising plant performance. (These are readily programmable in Excel.)
Model 1 (data correction)
- In order to obtain meaningful recovery data in a CIL/CIP plant allowance must be made for residence time and mixing in the plant
- A method of correcting data from composite plant samples (shift, half-day, daily) so that a good estimate can be made of the head truly corresponding to any particular tailings sample, will be described.
- Without such correction plant recovery data is virtually meaningless. With it correlation of performance data with major plant variables becomes possible.
Model 2 (plant simulation)
- A CIL/CIP plant simulation model which permits projections to be made of losses of values in tailings solids and in solution will be presented.
- The model can be used to consider such things as feedrate, plant configuration, carbon advance rate, use of leach only tanks, number of tanks, solution return from a thickener, etc.
- The model is based on plant studies of leaching rates and the equilibrium between active carbon and metal cyanides in solution.
