Lead-zinc mine is rich in metallic elements of lead and zinc minerals, and it has a wide range of applications, such as electrical industry, machinery industry, military industry, metallurgical industry, chemical industry, light industry and medicine and other fields. In addition, lead metal is widely used in the nuclear industry, oil industry and other industry. According to the nature of lead-zinc, it should be used the method of priority flotation, that is the technology of the first selection of lead after zinc selection.

Distribution of lead - zinc deposits

China's lead and zinc production layout is based on the distribution and construction conditions of lead-zinc ore. After years of development and construction, it is now formed lead and zinc mining and processing and matching production base in the northeast, Hunan, Guangdong and Guangxi, Yunnan, Northwest, where the lead production accounts is more than 85% of the total output, zinc production accounts is 95% of the total output. In addition, it is also built a number of small and medium-sized mines in Inner Mongolia, Jiangxi, Guizhou and other provinces. Overall, the resources of China's lead-zinc ore is rich, and has a good investment and development prospects.

Lead - zinc ore beneficiation technological process

It is the method of flotation that the whole lead-zinc ore beneficiation technological process, and lead and zinc separation is adopt the method of the first selection of lead after the election of zinc, than lead concentrate needs to be re-grinding after the selection process. In general, lead-zinc ore need to go through several major process of crushing, grinding, rough selection and flotation. Crushing is divided into two sections, one closed-circuit process; grinding with a closed-circuit grinding, lead ore to re-grinding; lead flotation with a float three sweep, coarse lead ore re-grinding after three selection; zinc flotation using a Rough three sweeping four fine process; the last lead and zinc concentrate after concentration, drying can be obtained after the lead-zinc concentrate.

What mining equipment is required?

According to the general production situation, ZK will equip some mining machinery to the lead-zinc ore beneficiation technological process configuration, including crusher, ball mill, and flotation machine, dryer and so on. During crusher, in general according to the particle size of the large stone, you can using jaw crusher for rough break, hammer crusher in the fine break; ball mill is mainly for grinding; flotation machine is the key equipment. ZK production of flotation machine has a lot of advantages that high precision, large capacity, and the volume per unit volume is as 2 to 3 times as the conventional flotation machine, small occupied area, saving infrastructure investment, low operating costs. ZK can design lead-zinc ore beneficiation process program according to the requirements of customers.
