Inside the ball mill, the crushed iron ore will grind the ore to about 0.2 mm with 3-inch steel balls. 3.This iron ore slurry is pumped to the agitation tank. This iron ore slurry is finally pumped to the flotation machine with the fine sulfide ore (~-0.074 mm) going to froth flotation cells for recovery of iron.

Ball mill is an energy-intensive device for grinding and breaking iron ore particles, which is extensively used in mineral, cement, chemical, and other industries.1–4 In the field of mineral processing, a portion of the energy is converted into heat that will raise the milling tem-perature and breakage characteristics of iron ore will

In all ore dressing and milling Operations, including flotation, cyanidation, gravity concentration, and amalgamation, the Working Principle is to crush and grind, often with rob mill & ball mills, the ore in order to liberate the minerals. In the chemical and process industries, grinding is an important step in preparing raw materials for subsequent treatment.

The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond's standard test procedure [].For each iron ore sample, the RT taken to produce 250% circulating load in the BBM was measured by a new method.

In comparison to conventional tumbling mills, i.e., rod-and ball mills, the grinding media in an AG mill derive from the feed ore itself (Gupta and Yan, 2016;Hahne et al., 2003).
