The original processing plant production process for the flotation process, lead and zinc recycling loop by a rough election after the first zinc lead, featured three times, twice scavenging composition, in order to return all mine, because some easy to float The zinc and sulfur minerals float on the lead cycle, so that the production must be subjected to heavy pressure and strong pulling operation, and the index is not satisfactory. In 1982, according to the small-scale experiment, the process was changed to branch-speed flotation (process and equipment configuration) as shown in the following two figures, and the technical indicators and economic benefits were significantly improved.

(1) Improved recovery rate The production index of the flotation process improved by more than one year of production practice is compared with the original process index (the same ore processed in the same period of last year or the same year), and the lead recovery rate is increased by 1 to 1.5%. With the continuous improvement and improvement of the zinc-sulfur mixed flotation process, the zinc recovery rate reached 84.28% in the first quarter of this year, which is the best level in history, as shown in the table below.
To obtain perfect joins, inside of the solder ring copper fitting and the outside of the copper pipe are cleaned using coarse steel wool, flux paste is applied, the pipe is then inserted into the fitting and heat applied from a portable propane torch until a ring of solder shows at the edges of the fitting.
