Latest Patents

Kuroiwa has developed a patent titled "Floatation Separation Of Copper And Molybdenum Using Disulfite." This method provides an effective way to separate copper ore from molybdenum ore. The process involves a conditioning step where disulfite is added to an ore slurry containing both copper and molybdenum ores. Following this, an ore flotation step is performed, allowing for selective flotation of the molybdenum ore. By increasing the hydrophilicity of the copper ore, a significant difference in hydrophilicity between the two ores is established, leading to efficient separation.
