“…Statistical estimates of the studied parameters are presented in Table 1 [6][7][8]. In the analysis of the source data, there is considerable variability in the extraction of precious metals: gold is in the range of 23-95% (the content of metal in the ore is 0.4-2.1 g/t), silver in the range of 20-88% (the content of metal in the ore is 4.3-55.3 g/t) [9] The correlation matrix for the studied array is presented in Table 2. The correlation matrix shows a negative correlation between the content of precious metals in the ore and their extraction into the copper concentrate [10,11].…”

in the conditions of significant variability of processed polymetallic ores of the Akbastau Deposit, it is essential to minimize the variability of technological indicators of enrichment. Due to the multifactorial nature and non-linearity of the flotation process, the use of classical regression models does not provide the necessary level of reliability, therefore, there is a significant variability in the extraction of precious metals. To solve this problem, the paper substantiates the use of the neural network modeling methodology, which allows to estimate the variability of gold and silver extraction depending on the variation of the content of metals in the ore.

“…The selection and sizing of the main technological equipment units for minerals comminution circuits is usually based on the required capacity, on the physical and mechanical properties of minerals, and on the required size distribution of the initial and final products of grinding [1][2][3]. The physical and mechanical properties of the ore can be described using different methods [4][5][6]. In Russia, the ore grinding calculations use the specific mill volumetric capacity by design size fraction (usually -0.074 mm) [7,8].…”

The paper addresses determination of ore hardness and grindability parameters using the data obtained from the industrial comminutions circuits survey campaigns. The calculations use the earlier obtained relations between the high-energy impact fracture parameters A and b from JK DWT and SMC tests and the energy efficiency indices used in the Morrell method for the conventional grinding, coarse grinding and high pressure grinding roll milling. Using the simulation modeling of comminution circuits for two types of sulfide copper-nickel ore and one type of apatite-nepheline ore, it is shown that the relative error of the theoretical determination of the JK DWT and SMC testing data is never higher than 16.1%. The calculation method is recommended for application in design and optimization studies of process plants for various genesis minerals, including iron ore.

“…The mutual infl uence of particles is also signifi cant, especially noticeable at high concentrations. Meanwhile, it was found that at the output of the chopping cutter (especially at large aggregate volumes), different size classes hada similar shape (and as a consequence, the shape ratio), so the infl uence of the shape in the criterion output can be neglected [6,7]. Mill drain usually contains intergrown pieces in the entire range of their unlocking (from ρ max to ρ min ) and size, then the selectivity ratio for unlocking intergrown pieces φ can be calculated from the expression: here λ is the volume content of a mineral with a density of p max or p min .…”
