Sapphires, a kind of precious blue corundum, are prized for their captivating blue color and hardness. As natural sapphires are typically embedded within various minerals, an efficient process is required to wash them. The sapphire washing line typically consists of feeders, washing machines, pulsator jigs, and dewatering screens. Sapphire Washing Process 1. Cleaning and Screening The raw ore is first […]
Corundum is primarily used for high-grade grinding materials, as well as bearing materials for watches and precision machinery. Aside from the star effect, only semi-transparent or transparent corundum with vibrant colors can be used as gemstones. Red corundum is known as ruby, while other colors are collectively referred to as sapphires. Natural corundum is often
Sapphire, excluding ruby, is a collective term for colored corundum gemstones, primarily composed of aluminum oxide. As a mineral crystal, sapphire occurs at low concentrations in its ore and requires mineral processing equipment to be separated from gangue and river sand. 1. Gravity Separation of Sapphire Sapphires have a specific gravity of 4.0-4.1, significantly
1. Calcite-Fluorite Ore Calcite-fluorite ores primarily consist of fluorite and calcite (with calcite content often exceeding 30%), with minor amounts of quartz, forming quartz-calcite-fluorite ores. Due to the similar surface physicochemical properties of calcite and fluorite, which are both calcium-containing minerals, mutual transformation between these minerals can occur when they coexist in solution, making separation

1. Quartz-fluorite Flotation Process Quartz is the primary gangue mineral in quartz-fluorite ores, where the fluorite content is relatively high, reaching up to 80%. A common fluorite flotation processing flow involves coarse grinding followed by one stage of rougher flotation, then regrinding the rough concentrate and performing multiple stages of cleaner flotation. In the quartz-fluorite

1. Barite-fluorite Ore Flotation Process Barite-type fluorite ores primarily contain barite as a gangue mineral (usually 10-40%) and are often associated with minor sulfide minerals (pyrite, galena, sphalerite), with some deposits containing a higher quartz content. Given the similar floatability of barite and fluorite, a flotation process involving the preferential bulk flotation of fluorite and

1. Sulfide-fluorite Flotation Process The associated metallic minerals in sulfide-type fluorite ores often include chalcopyrite, pyrite, galena, and sphalerite. Flotation processes typically aim for the comprehensive recovery of these minerals. Due to the significant differences in surface properties between sulfides and fluorite, collectors like xanthates and dithiophosphates are commonly used to preferentially float sulfides, followed
