Flotation agent

    Due to the many different characteristics of grain-retaining grains from normal flotation grain size, these characteristics deteriorate the flotation environment of grain-retaining pulp, so that fine-grained ore can be treated with conventional flotation agents, and the flotation effect is often not good. Through the analysis of the causes of fine-grained floating, many ore-dressing workers are engaged in the research and development of flotation agents with high efficiency and strong selection performance.

    In view of the characteristics of lead-zinc micro-particles of a mineral processing plant in Guangxi with large specific surface area, high specific surface energy, difficulty in sedimentation and difficult separation,

After flocculating the fine-grained lead-zinc minerals with a new selective flocculant Bs, flotation and separation were carried out to recover the lead and zinc recoveries of 76.14% and 81.21%, respectively.

    With a new type of activator MoH flotation Panzhihua Micro Threocean Chin, the results of industrial tests. Compared with the use of another new type of collector MoS, the recovery rate can be increased by 6.22%.

    The new type of collector ROB developed was used for the 48% floatation of Panzhihua fine-grain Qin iron ores with good recovery of 75%. Compared with the original collector, the grade of concentrate button is increased by o. 65%, the recovery rate increased by 7.3%, the cost of flotation agent per ton of titanium concentrate decreased by 40.54 yuan, and the economic benefit was significant. Industrial tests have obtained concentrate grades.

    Modification of the conventional collector alkyl sulfonates to make ethoxylated sulfonates can increase their selectivity. P. Sormasand

(P.somasundaran) studies have shown that the use of potassium oleate and ethoxylated sulfonate sulphonates selectively captures collophane ores and selectively traps dolomite at low pH.
