At present, more than 80% of copper in the world is made by fire method, and it is mainly used to process copper sulfide ore. Pyrometallurgy is to melt copper ore (or calcine, agglomerate, etc.) and flux at high temperature, or directly smelt into blister copper, or first smelt into matte (melt mainly composed of copper, iron and sulfur) Then smelt into blister copper. Except for some operations (...

1. The raw material tape needs to be wound along the thread direction, which greatly reduces the sealing performance. 2. Do not wrap all threads with raw material tape. In addition to avoiding the raw material tape from entering the pipe, it will also reduce the sealing performance. It is recommended to start winding from the second thread at the beginning of the thread, leaving the first thread o...
