Nowadays,although China has the most abundant mineral resources in the world.But the fact is that most of the mineral resources in China was the low-grade,low-quality one.In this context, mining recovery rate, mineral processing recovery rate, and comprehensive utilization rate have become key technical indicators to solve the resource dilemma.

一、The Introduces of Mining Recovery Rate and Mineral Processing Recovery Rate

The mining recovery rate is an indicator that measures the proportion of ore actually extracted from the recoverable reserves. The high or low recovery rate directly affects the lifespan of the mine.

Taking an iron mine with a reserve of 100 million tons as an example, if the recovery rate is increased from 80% to 90%, it is equivalent to "saving" 10 million tons of ore, which not only extends the service life of the mine, but also dilutes the mining cost.

When ore is transported out of the mine, the mineral processing recovery rate becomes an amplifier of resource value. This process is like sorting gold from sand, extracting the target mineral from the messy raw ore through processes such as crushing, grinding, and sorting.

Taking copper mines as an example, if the recovery rate of ore dressing is increased by 7 percentage points (from 85% to 92%), about 50 tons of copper concentrate can be produced per 10000 tons of ore, directly increasing the revenue by millions of yuan. For low-grade ore deposits, high recovery rate is the lifeline of project profitability.

二、Comprehensive Utilization Rate: the Ultimate Answer to Resource Recycling

After the main mineral is extracted, the remaining tailings, waste rock, and associated resources are often considered as "trash". And the comprehensive utilization rate is precisely to reintegrate these "misplaced resources" into the value chain.

Taking coal gangue from Shanxi and Inner Mongolia as examples, mining companies use Mingde Optoelectronics intelligent sorting equipment to select kaolin from coal gangue, which can be used as refractory materials and double the value of tailings resources. This model of 'eating it clean' is rewriting the stereotype of 'Roughly production' in mining industry.

三、Future Picture:Sustainable Mining Industry in China

Driven by the dual carbon strategy, the "three rates" have been upgraded from assessment indicators to core competitiveness in the mining industry. Through technological innovation by some mineral processing enterprises, China is shifting from "mining to sell resources" to "technology for resources": for every 1% increase in mineral processing recovery rate, it is equivalent to discovering a medium-sized mine; Every 10% increase in comprehensive utilization rate can reduce carbon emissions by 30%.

In the future, with the maturity of technologies such as intelligent sorting and in-situ extraction, mining will truly become a "resource sustainable" green industry.
