Abstract

The influence of flotational enrichment on the economic performance of Abashevskaya enrichment facility between 2013 and 2024 is investigated. Operational data for the enterprise are analyzed: for example, the throughput of coal of different ranks; efficiency of equipment use; the rock content of the concentrate; and the variation in concentrate yield. The results show that the introduction of flotational enrichment in 2019 greatly improved the plant’s economic performance. In particular, the coal throughput, the efficiency of equipment use, and the concentrate yield increased, while the rock content of the concentrate fell. Note that large coal fractions were mainly processed before the introduction of flotation, whereas slurry processing was possible afterward. That expanded the range of inputs that may be processed. The analysis indicates successful adaptation of the enterprise to the new technology and optimization of the flotation process for specific conditions. Further innovations to improve the enrichment efficiency should be developed.

煤炭浓缩设施加工效率的战略管理

研究了2013 - 2024年浮选富集对Abashevskaya富集设施经济效益的影响。对企业的经营数据进行分析：例如，不同等级煤的吞吐量；设备使用效率；精矿含石量；以及精矿产量的变化。结果表明，2019年引入浮选富集后，该厂的经济效益得到了较大改善。特别是煤的吞吐量、设备使用效率和精矿产量增加，而精矿中岩石含量下降。需要注意的是，大的煤馏分主要是在浮选之前处理的，而矿浆处理则是在浮选之后进行的。这扩大了可以处理的输入的范围。分析表明，该企业成功适应了新技术，并针对具体情况对浮选工艺进行了优化。应进一步开展创新以提高富集效率。
