preparation Embodiment 1

[0020] 1) Preparation of emulsified kerosene: emulsifier (a mixture of Tween-20 and PEG-400 at a mass ratio of 1:1), kerosene and water are mixed at a mass ratio of 1:15:70, and the ultrasonic frequency is 20~40kHz. Emulsify for 40~50min;

[0021] 2) Mix tert-dodecanethiol (purity higher than 95%) and the emulsified kerosene prepared in step 1) at a mass ratio of 1:1, and use ultrasonic vibration to make it fully mixed. The ultrasonic frequency is 20~40kHz, and the mixing time is It takes 20~30min to prepare a mixed collector.

[0022] The prepared mixed collector can exist stably in the form of emulsion at room temperature for 60 minutes, and after adding water, the emulsion droplets d 50 Basically no change; foaming is good, the foam is small and uniform.

Abstract

The invention relates to a lead-antimony-zinc sulfide ore bulk flotation collecting agent and preparation and application thereof. The gearbox left box body shell is prepared by mixing tert-dodecyl mercaptan and emulsified kerosene. The mass ratio of the tert-dodecyl mercaptan to the emulsified kerosene is 1:(0.9-1.2). The lead-antimony-zinc sulfide ore bulk flotation collecting agent has the better collecting effect on sulfide, and can be applied to lead-antimony-zinc sulfide ore bulk flotation. The lead-antimony-zinc sulfide ore bulk flotation collecting agent has the good foaming property, can adopt a small amount or no foaming agent, and can decrease the consumption of an activating agent copper sulfate; compared with traditional MA or single use of emulsified kerosene and tert-dodecyl mercaptan, the grade and recycling rate of sulfide can be increased, and types and consumption of medicament are reduced.

Description

technical field [0001] The invention relates to a lead-antimony-zinc sulfide ore mixed flotation collector and belongs to the technical field of mineral processing. Background technique [0002] Chehe Mineral Concentrator, Nandan County, Guangxi, its ore field is a lead-antimony-zinc polymetallic sulfide deposit mainly composed of cassiterite. Iron ore, pyrite, mainly recovered: cassiterite, lead antimony and zinc. The currently adopted process is: gravity separation-flotation-gravity separation process, in the flotation part, large doses of collectors, activators and foaming agents are used to remove sulfide ore, creating conditions for post-gravity cassiterite, among which, The collector is MA, the activator is copper sulfate, and the foaming agent is No. 2 oil. [0003] Due to the large amount of chemicals used, the variety of minerals in the ore, and the complex symbiotic combination, there are not only problems such as environmental pollution and unstable recovery rat...
