Oman chromite sample assays ~30% Cr₂O₃. Magnet separation failed at three field strengths, so gravity was used: grind to 100% passing 32 mesh, shake three fractions, recover -200 mesh slimes with centrifugal concentrator. Final concentrate hits ~42% Cr₂O₃....
In 2024, Xinhai Mining successfully undertook and implemented the 1000t/d gold processing plant project in Zimbabwe. ...
The tailings processing capacity of this project was 1500t/d, and the average tailing concentration was 28%.Flotation tailings were transported to the rubber pump box of the dry drainage workshop by self-flow or pumped...
The ore had a simple composition, primarily comprising fluorite, quartz and calcite. Major chemical components were CaF2 (28.30-87.49%, an average of 58.19%) and SiO2 (8.18-65.38%, particularly 25-38%, an average of 34.11%). The relationship between CaF2 and SiO2 was negative, which accounted for 92-95% of the total....
Major minerals were potassium feldspar and albite, which accounted for 60-80%. In white-flesh pink color, potassium feldspar occurred in the form of subhedral plate. Some crystals had cross-hatched twinning. The secondary mineral was quartz accounting for 10-30%, which was in milk white color and occurred in irregular and wormlike form. There was a minor amount of black mica, which occurred in the form of black flake and accounted for 1-5%. White mica occurred in the form of white flake and accounted for 1-5%. Magnetite and tourmaline occurred locally in black plate form....
The Vietnam 800t/d graphite mineral processing plant was an EPC+M+O project. The major mineral was graphite granulite, while the second one was graphite schist. The major beneficial mineral was medium flaky graphite which had a much better ability of beneficiation....
