Even South copper oxide ore, when high grade ore (6-11%) Using L - recycling electrowinning copper leaching rate, to reach 93-98% copper. In the mined ore, there are some low-grade copper oxide ore containing 1.34% copper, of which copper oxide accounts for 73.13%, combined copper accounts for 16.42%, and copper sulfide accounts for 10.45%. It must be firstly enriched by flotation and then re-concentrated. Leaching. We have carried out the ore dressing test on the ore. The process flow is: grinding the ore to -200 mesh, accounting for 64%, using sodium sulfide as the adjusting agent, using the diced xanthate and hydroxamic acid as the collector, and the 2# oil as the starting agent . The foaming agent is subjected to a rough selection and one sweep to obtain a coarse concentrate. The yield of the coarse concentrate is 20.75%, the copper content is 6.13%, and the recovery rate is 83%.
Automotive mold frame: industry status, technology trends and future prospects
The automobile mold frame is an important part of the automobile manufacturing process, which not only has a crucial impact on the appearance and performance of the automobile, but also an important guarantee for the efficiency and quality of the automobile production. This paper will introduce the concept, function, industry status, technology trend, application scenario, management strategy and future outlook of automobile mold frame in detail.
Overview of the car mold frame
Automobile die frame is the core component of automobile die, including upper die, lower die, side die, bottom die and so on. The main role of the car mold frame is to accurately manufacture various parts of the car according to the product design requirements, such as the car door plate, the engine cover, the trunk cover, etc. The design and manufacturing process of automobile mold is directly related to the quality and production efficiency of automobile products.
Second, the status of the automobile mold industry
With the rapid development of the automobile industry, the automobile mold industry has also made great progress. At present, the global car mold market has formed a pattern dominated by Germany, Japan, the United States and other countries. These countries have advanced mold manufacturing technology and equipment, which can produce high-quality automobile mold frames.
In our country, the automobile mold frame industry has also made remarkable development in recent years. Domestic enterprises continue to introduce advanced mold manufacturing technology and equipment to improve production efficiency and quality.
