According to statistics, the mining industry accounts for approximately 11% of the world's total energy consumption, making it a high-energy industry. For ore processing plants, energy efficiency and consumption reduction are crucial factors for sustainable development. In the production process of ore processing plants, crushing and grinding operations consume roughly 60% of the energy. Optimizing and adjusting the crushing and grinding processes to reduce the amount of ore in the grinding stage and increase grinding efficiency is essential. Achieving more crushing and less grinding and determining the appropriate amount and granularity of ore to be fed into the mills can effectively enhance production efficiency, reduce energy consumption, and ultimately improve the economic and ecological benefits of ore processing plants.

More Crushing and Less Grinding Leads to Early Discard

For existing ore processing plants with fixed crushing and grinding equipment, it is possible to optimize the various crushing stages by adjusting the crushing and grinding capacities while ensuring the foundational crushing process. This optimization maximizes the capabilities of the crushing system, leading to reduced granularity and reduced pressure on the grinding stage, thus increasing grinding efficiency.

Optimizing the ore crushing and grinding processes often involves methods such as optical and magnetic separation and gravity separation. Pre-sorting the ore not only enhances the original ore grade but also reduces the quantity of ore entering the crushing and grinding stages. This significantly improves grinding efficiency and reduces energy consumption. Moreover, substantial savings in transportation and sorting costs can be achieved, unlocking the production capacity of ore processing plants and extending the lifespan of tailings storage facilities.

Optimizing Grading Efficiency by Considering Mineral Characteristics

To ensure the scientific and rational grading granularity, many ore processing plants employ closed-circuit grinding and grading systems during production. However, over-grinding is a common issue during the production process and is a major reason for the high energy consumption in ore processing plants. Achieving scientific and rational grading granularity requires optimizing the size of graded ore according to the ore's associated minerals and liberation degree to avoid over-grinding and reduce energy consumption during grinding.

Comprehensive Utilization of Ores

To maximize the utilization of various components in ores, ore processing methods should be employed to process useful minerals into independent products for comprehensive recovery.
