Experimental Research on Mineral Processing of High-sulfur Refractory Molybdenum Ore

High-sulfur refractory molybdenum ore presents a challenge for mineral processing due to the fine dissemination of molybdenum minerals and the presence of sulfur-bearing minerals. Various experimental studies have been conducted to develop effective mineral processing methods for these types of ores. Here are some highlights of experimental research on mineral processing of high-sulfur refractory molybdenum ore:

1. Study on Grinding and Classification Process: A study was conducted to investigate the effect of grinding and classification on the flotation performance of high-sulfur refractory molybdenum ore. It was found that a finer grinding size and a reasonable classification could improve the flotation recovery of molybdenum.

2. Roasting Process: Another approach to mineral processing of high-sulfur refractory molybdenum ore is roasting. A roasting process was developed to remove the sulfur from the ore before flotation. The results showed that the roasting process improved the flotation performance of the molybdenum, but there were still issues with high sulfur content.

3. Desulfurization Prior to Flotation: A desulfurization process was developed to remove the sulfur from high-sulfur refractory molybdenum ore before flotation. The results showed that the desulfurization process significantly improved the flotation recovery of molybdenum.

4. Combination of Roasting and Desulfurization: A combination of roasting and desulfurization has also been proposed as a method for processing high-sulfur refractory molybdenum ore. The roasting process removes the sulfur, while the desulfurization process ensures that the sulfur is completely removed before flotation. The combination process has been shown to effectively improve the molybdenum recovery rate.

Overall, experimental research on mineral processing of high-sulfur refractory molybdenum ore has shown that various approaches can be effective, but fine-tuning the processes for a specific ore type is necessary to achieve optimal results.
