  Process optimization of a chrome ore gravity …

  2020525 · This innovative methodology has brought insight into the behaviour of certain species (chromite and silicates) of minerals in the circuit. This approach has not only resulted in the reduction of chrome losses (<12% Cr2O3) but also the concentrator achieved a stringent target SiO2 grade of 3.27% in the concentrate.

  The Common Gold Mining Process – Gravity Separation …

  2019124 · 5. Separating Cone Process. Separating cone is developed based on the principle of pinched sluice (also known as fan chute). The pinched sluice is fan-shaped,with a length of about 1 meter, a width of 125-400 mm at the feed end and 25-9mm at the drain end. Pulp from the center of the upper end into the distribution cone distribution into the ...

  Mineral Processing Method of Low-Grade Siderite and …

  2023724 · Siderite and limonite are important iron ore resources, but the iron ore grades in these two ores are low. With the gradual excavation of resources, the development and utilization of low-grade iron ore resources have gradually attracted attention. Therefore, the rational development and utilization of siderite and limonite is of great significance to …
