In the realm of the lead zinc flotation process, the beneficiation of lead-zinc sulfide ores presents unique challenges due to the presence of minerals like galena, sphalerite, pyrite, and chalcopyrite. The primary goal is to not only recover valuable minerals but also to selectively separate them into smeltable products. Over the years, the extraction of […]

Mr. Wilfredo Moncano, Director of the Bureau of Minerals and Geosciences of the Philippines, confirmed that Roy Cimatu, Minister of Environment and Natural Resources, has signed an executive order lifting the ban. Now, the doors are open for commencing open – pit gold mines, which is set to reshape the country’s mining landscape. The Philippine […]

The lead and zinc mining industry deals with ore of lead and zinc, which is a relatively difficult one to handle. In general, lead-zinc ore in the context of lead and zinc mining is leaner and the associated components are more complex than rich ore. Therefore, in the beneficiation industry within lead and zinc mining […]

Cuprite is an oxide mineral characterized by its low hardness, high density, and distinctive red color. It is formed through the weathering of copper sulfide and typically exhibits a high ore grade. The copper flotation process is the most widely used beneficiation technique for cuprite ores. The primary recovery methods include conventional sulfide flotation, hydrothermal […]

In the mineral processing industry, many concentrators encounter the issue of significantly reduced classification efficiency in their screw classifiers. The primary cause of this problem is the disordered settling of fine and heavy ore particles alongside coarse and light particles during the classification process. This leads to the phenomenon of “equal fall,” where fine particles […]
