Comminution and classification technologies of iron ore
Most of the high-grade hematite iron ores are typically subjected to simple dry processes of crushing and classification to meet the size specifications required for direct shipping ore (DSO). This involves multistages of crushing and screening to obtain lump (−31.5 + 6.3 mm) and fines (approximately −6.3 mm) products.

Cation Exchange Capacity and Base Saturation
Published with Full Review on Sep 08, 2022. Cation exchange capacity (CEC) is a measure of the total negative charges within the soil that adsorb plant nutrient cations such as calcium (Ca2+), magnesium (Mg2+) and potassium (K+). As such, the CEC is a property of a soil that describes its capacity to supply nutrient cations to the soil …

Introduction to Mineral Processing or Beneficiation
4.2 Classification. Sedimentation and Hydraulic Classifiers. Free settling classifiers are essentially large pools, ponds or conical bottomed tanks with a free settling zone. The coarser particles sink and are removed from the bottom of the settling zone. These units are simple in design but often inefficient in sorting and sizing.
A Convolutional Neural Network of GoogLeNet Applied in Mineral
This illustrates that the fusion model can achieve a superior success rate in a smaller prospective area. As shown in Figure 10b, the success rate curve of the fusion model was divided into three levels to evaluate the predictive capacity of mineral prospectivity mapping. The first level was the high-prospectivity area, in which the …
