mining equipment grinding and flotation circuits

open-circuit grinding, closed-circuit grinding - Xinhai

Therefore, closed-circuit grinding has the characteristics of high productivity, light degree of over-crushing, fine and uniform distribution of particle size. Generally speaking, flotation plants and magnetic separation plants mostly adopt closed-circuit grinding processes. The open-circuit grinding is suitable for the first grinding.

Modeling the product net value of a grinding-flotation circuit

Abstract. This paper presents an economic model of a grinding-flotation mineral processing plant. The model is used to calculate the profit of the plant by subtracting the operating costs from the net-smelter-return. The former is composed of the fixed costs and the major variable costs: grinding media and energy consumption.
