DF Collectors Catalog:
DF-401 compound collecting agent exhibits high selectivity and can form stable chelate with tungsten, titanium, iron. It is suitable for the flotation of metal oxide ores and nonmetallic minerals, especially for refractory tungsten, titanium, iron and phosphorus minerals. Compared with other single collecting agent, it can achieve better target. It can also get higher recovery while concentrate grade is proper. DF-336 desulfuration collecting agent is suitable for the desulfuration flotation of polymetallic minerals, especially for sulfur-rich iron, tungsten, tin minerals. Compared with other collecting agent, it can achieve better target. It can be added directly without changing the flotation process, and its dosage depends on the minerals treated, is about 100~400g/t, especially in acid condition. DF-341 compound collecting agent is suitable for the flotation of sulfide minerals and poly-sulfur mixed ores, especially for copper sulphide ores, zinc sulphide ores, zinc oxide ores, pyrites, pyrrhotite, marcasite. It has better collecting capacity than amyl xanthate, especially for poly-sulfur mixed ores. DF-341 compound collecting agent is suitable for the flotation of sulfide minerals and poly-sulfur mixed ores, especially for refractory copper sulphide ores, poly-sulfur mixed copper ores, poly-sulfur mixed lead-zinc ores. Compared with other single collecting agent, it can achieve better target. DF-347 compound collecting agent is suitable for the flotation of sulfide minerals and poly-sulfur mixed ores, especially for sulfur-rich copper sulphide ores and zinc sulphide ores. It can be added directly without changing the flotation process, and its dosage depends on the minerals treated, is about 30~80g/t. DF-348 activators has special active molecular structure, and it is suitable for the flotation of refractory copper oxide ores, and it displays strong collective power and rapid flotation, low dosage. DF-353 compound collecting agent is applicable for the flotation of gold, silver sulphide ores and poly-sulfur mixed ores, especially for refractory ores which has gold and silver. Compared with other single collecting agent, it can achieve better target. DF-388 compound collecting agent is suitable for the flotation of nonferrous metals oxide minerals and poly-sulfur mixed ores, especially for refractory copper oxide ores and poly-sulfur mixed lead-zinc ores. Compared with other single collecting agent, it can achieve better target. It can also get higher recovery while concentrate grade is proper. (Because DF-388 compound collecting agent has some frothing property, so it is advisable to reduce the dosage of frother due to the field process.)
