Introduction to copper, lead and zinc ore dressing process and equipment

[Technological advantages]

Adopting a mixed flotation concentrate regrinding process can reduce grinding costs and is easy to manage

[ Application Fields]

The process of using mixed flotation concentrate regrinding is generally suitable for copper lead zinc sulfide ores with close symbiotic relationships, difficult dissociation, and uneven particle size distribution.

[Technological advantages]

Innovative process flow and lower operating costs

The re grinding process of copper lead mixed concentrate does not require all the raw ore to be finely ground, saving grinding costs. At the same time, the re grinding of concentrate further dissociates the monomers of copper lead concentrate and has a good de drug effect, creating favorable conditions for the separation of copper and lead.

Customer Example 1

A lead-zinc beneficiation plant in China has a design capacity of 600000 tons per year, with a daily processing capacity of 2400 tons and an annual working days of 250 days. The project is divided into two phases: the first phase has a design capacity of 300000 tons per year, with a daily processing capacity of 1200 tons, and the second phase has a design capacity of 300000 tons per year, with a daily processing capacity of 1200 tons. The mineral processing method used in the project is flotation, and the product plan includes two types of products: lead antimony concentrate and zinc concentrate. The main design indicators are: yield, lead antimony concentrate 10.9%, zinc concentrate 2.58%; Concentrate grade: lead antimony concentrate with Pb32.17%, Sb28.11%, zinc concentrate with Zn59.9%; The recovery rate is 85.11% for lead antimony concentrate, 82.59% for Sb, and 88.82% for zinc concentrate.

After the establishment of a lead-zinc ore beneficiation plant in Africa, the on-site process was continuously improved and perfected, and the process indicators were significantly improved. However, in the later stage, due to the deepening of mining depth, the ore properties changed significantly, and the grades of lead and zinc concentrates decreased significantly. The original priority flotation process can no longer meet the separation requirements of the copper lead zinc ore. Therefore, the beneficiation plant has entrusted Xingkuang Group to carry out process transformation. After repeated beneficiation experiments, Xingkuang Group has decided to adopt a mixed flotation process, prioritizing the flotation of copper lead concentrate, which is then ground and floated. At the same time, Xingkuang Group's self-made equipment is used to replace the original flotation machine with Xingkuang Group's full section air lift microbubble flotation machine. After this transformation, the main process indicators of the beneficiation plant are as follows:

XKJ Group copper, lead and zinc beneficiation and processing technology can focus on the comparison of schemes, investment costs and comprehensive utilization of minerals. Nearly 100 cases have been completed at home and abroad, and its process results have been well received by international customers. Among these copper, lead and zinc mine application cases, the most representative one is the copper, lead and zinc mine of a company in Xinjiang. The mine has a close symbiotic relationship and a small particle size. With the original process, the copper and lead concentrates contain excessive amounts of each other, affecting the economic benefits of the enterprise. XKJ Group improved the process and selected efficient equipment, with excellent final indicators and achieved standard production.
