May 04, 1999 The OP formula is an evaluation of the flotation and cyanidation processes. This formula was made to be able to determine the situation in the flotation circuit while being able to anticipate the cost in the cyanidation process. OP is therefore able to bring an economical link between the flotation circuit and the cyanidation process.
