| Introduction | sodium isopropylxanthate is a non-ferrous sulfide ore collector with strong collecting power and good selectivity, widely used in copper, molybdenum, zinc sulfide mineral flotation, gold bearing pyrite flotation collecting effect is better. It has obvious advantages in improving the gold recovery rate of gold ore and copper-gold ore, and can also obtain satisfactory results for refractory copper-lead oxide ore. Commonly used in rough selection and scanning process. |
| Application | The collecting capacity of sodium isopropyl xanthate in the flotation of non-ferrous metal sulfide ores is slightly stronger than that of ethyl xanthate. It is mainly used as a collector for the flotation of various non-ferrous metal sulfide ores, and can also be used as a precipitant for hydrometallurgy and as a rubber vulcanization accelerator. |
| Application | mainly used for flotation collection of various non-ferrous sulfide minerals |
