It is become the conjunct developing direction in international society to develop low carbon economy with scientific supporting. And coal mine is usually produced by high carbon company, so it’s a great question to adopt low carbon economy development, which require immediately solve.
The coal resource exploiting produce vast high carbon product on one side, on the other side, it caused mine area ecological pollution with environment waste such as vast waste water, gas and slag in producing process. The ejected gangue will have spontaneous combustion, which eject vast toxic gases and greenhouse gases. The exploiting causes land dig and loss. The collapse land directly pollutes environment. For a long time, the mine industry gives us a reflection that gangue pile high, earth surface is loss and collapsed as well as polluted water running all around the mine, etc.
Coal industry develops at the cost of destroy ecological environment. So, the key point for coal industry low carbon developing is changing developing manner, which is scientific developing. We should obey the rule of low carbon economy and recycling economy design and demand with its new manufacturing managing ways, which respects on the following six aspects:
1. Increase innovation of mining geology and exploiting technology as well as resources utilization rate;
2. Strengthen reclamation management of coal mine area ecological environment and restoration, achieving mining simultaneous with management.
3. Adjust industrial structure, increase beneficiation, pit power generation and mine waste compound utilization and achieve recycling economy.
4. As a whole new developing pattern of low carbon economy, low emission is not only the strategic choice, but also is the option for mine industry with continuous develop. We should change high energy consumption, high pollution and low efficient developing model into low energy consumption, low pollution and low emission developing method. And the first developing manner choice will be resource saving, environment friendly low carbon developing pattern;
5. Increase innovation of underground mine filing technology and decrease coal gangue occupying area and environmental pollution.
6. Strengthen analyzing of mine area water resources and protect mine water compound handling and utilization to achieve water resource protective exploiting and mine water zero emission.
Low carbon economy is a great progress from industrial civilization to ecological civilization. The building of low carbon ecological mining is combine put human environment, ecological environment, resource environment and technology economic environment together. Rebuild the mine exploiting with low carbon and environmental industrial system at minimum cost to achieve maximum resource and economy profit. After the extracting, using minimum end management make mine engineering and ecological environment as a whole.
Spodumene: According to the hard rock crushing process, the crushed product is generally 5-40mm, combined with different design requirements of customers, two-end or three-stage crushing, high-grade crushed products (above 4-5%) can be directly used in the metallurgical process to produce lithium carbonate Or lithium hydroxide, the particle size of the finished product is generally around 20-40mm; low-grade generally requires ball mill grinding and separation, and the particle size of the finished product is generally around 5-20mm;
