Establish a mass balance and derive an expression for the circulating load. 19.3. A copper sulphide ore was crushed and milled in close circuit with a classifier. The overflow from the classifier fed a rougher cleaner flotation circuit at the rate of 500 t/h. The ore assayed 2.75% Cu. The recirculating load in the flotation circuit was 270%.

Live Chat### Circulating Load Calculation Formula

Here is a formula that allows you to calculate the circulating load ratio around a ball mill and hydrocylone as part of a grinding circuit. For example your ball mill is in closed circuit with a set of cyclones. The grinding mill receives crushed ore feed. The pulp densities around your cyclone are sampled and known over an 8hour shift allowing to calculate corresponding to circulating load

Actually with the recirculating load of about 250300% your operations are fine on the ball mills. You only experience high recirculating loads if there is a change in the material being treated meaning the Bond work index tends to be higher for the new material.

ABSTRACT The run of mine ore from Aghdarreh gold mine must be comminuted to achieve the desired degree of liberation of gold particles. Currently comminution circuits include a singlestage crushing using a jaw crusher and a singlestage grinding using a SemiAutogenous Grinding (SAG) mill in closed circuit with a hydrocyclone package.

A problem for solving mass balances in mineral processing plants is the calculation of circulating load in closed circuits. A family of possible methods to the resolution of this calculation is the iterative methods consisting of a finite loop where each iteration the initial solution is refined in order to move closer to the exact solution.
