The transformation is compared through various configuration schemes. Determined to still be divided into three series, and maintain the original structure of the process, that is, a clean sweep. The new type of BF flotation machine (BF4.0m334, BF1.2m3
62 units) are installed adjacent to it, with an elevation of 8.65m. It has a length of 144m and a width of 6m (this plant spans 15m) in the idle factory space. (This plant was originally installed with a 7A (volume 5.8m/set) sulfur removal flotation machine. This flotation machine was replaced in 1993-1996.
KYF24m3 and XCF24m3 external pneumatic mechanical stirring flotation machine. As the volume of the flotation machine becomes larger, a lot of plant area is saved. This configuration has three advantages: First, it can use the original 7A flotation machine equipment foundation, which can save investment and shorten the construction period; second, the position of the re-mill and cyclone equipment elevation is not changed, and the composite crusher can still ensure the new installation. Equipment slurry self-flow, process flow; the third is to take "-" shaped arrangement, neat appearance, ease of operation and equipment maintenance, is conducive to the loss of all metal recycling.

According to the actual molybdenum selection process, we dare to boldly change the local equipment structural parameters of the “BF” flotation machine. For example, the ore discharge method and the size and position of the discharge port have been changed. Production practices prove that this change is scientific, effective and successful. This move also laid the foundation for the success of the new process. In order to facilitate the future production technology management and process flow examination, the tailing tank of the flotation machine was decisively improved, and a sampling box between each operation was added. In order to prolong the service life of the equipment, eliminate the loss of metal and reduce the operating expenses of the equipment. At the same time when the equipment is installed, the phases of the floatation machine are protected against wear. In other words, a 25mm thick cast stone is laid on the bottom of the cell, and the wear-resistant composite material is lined on the inner side of the floatation tank and on the inner wall of all the process piping to ensure that the flotation machine will not leak for at least 15 years. Large-scale scientific optimization of production process parameters is another important factor that guarantees the success of this transformation.
