GMSA is the leading supplier of the grinding media requirements for the Southern African mineral processing industries, with exports to many African countries and more recently to Australia. The GMSA production facility has been producing and supplying grinding media for more than 70 years.
High chromium grinding media are iron balls with a diameter of 10mm 12mm, that are used to grind copper and silver ores in industrial mills. They are used to maximize copper ore recovery from extracted materials. The chromium content in grinding me dia has a huge impact on the recovery rate of the flotation process. When the chro
The selection of chrome ore mining equipment is closely related to the physical and chemical properties of chromium ore. Because chromite is weakly magnetic, with the continuous improvement of high intensity magnetic separation technology, the technology of purifying chromium ore with high intensity magnetic separation has been very mature.
Different alloys are recommended depending on ore type and mill particulars in order to arrive at the most cost economic solution. Based on our world wide experience, AIAE can help select optimum alloy for specific application ranging from Chromium 10 to 32 % and Hardness ranging from 58 to 69 RC.
The high chrome white iron media contains a significant amount of chromium , and thus these types of media are also commonly called high chrome grinding media . High chrome media has a higher hardness and higher corrosion resistance than low alloy steel media.
Like mining, beneficiation for chromite depends on the characteristics of the ore deposit and on the mining methods used. For example, an operation extracting only high grade ore may require only hand sorting and screening.
The metallurgical impact of using an inert grinding media on the flotation of UG2 ores Laboratory study Greet presented a laboratory study completed on UG2 ore. The data in Table 1 indicate that changing the grinding media from forged steel to high chrome produced an increase in the Eh to more oxidizing pulp potentials by greater than ...
