1. Mineral processing energy consumed in the pulverization process the total energy consumption of 50 to 70% or higher, generally mineral processing to alter the physical properties of the mineral (mineral particle size and concentration of minerals) to meet the requirements. To find a more effective way to reduce fossil energy consumption during processing, simplified material physical changes can improve the economic efficiency of the entire process.

　　2. The mineral particles localized heating caused by micro-cracks and brittle material will lead to more efficient grinding, the use of microwave heating to enhance this localized heating. The mineral particles of high energy during prolonged heating (in seconds) or increase the phase or chemical change caused by thermal energy, thus generating more internal stresses and improves the next step. Studies have shown that microwave radiation is an effective method of improving mineral grinding, because the microwave increased mineral transgranular and intergranular fracture.

　　3. Microwave mineral processing tailings in the mining crushing process in the presence of a potential to reduce energy consumption advantages, manifested in changing the surface chemistry of minerals and promote a new smelting method in the more controlled environment is formed. If fully applied microwave technology, so that each mineral can be processed by the microwave will reduce operating costs throughout the mining industry. Increase or directly to easily and efficiently reduced by 25% ground using microwave energy costs during the grinding process of transmission.
