5results about How to "Improve flotation recovery" patented technology

This utility model discloses a flotation cell, belonging to the field of flotation cell technology. It includes a cell body and an aeration structure. The cell body has through-slots and locking slots on its left and right sides, respectively. Bottom baffles and top baffles are respectively provided at the bottom and top of the through-slots. The aeration structure includes a connecting pipe, a movable cover, an aeration pipe, and an aeration pump. The connecting pipe is located at the bottom of the cell body, the movable cover is located at the bottom of the outer surface of the connecting pipe, the aeration pipe is located at the bottom of the movable cover, and the aeration pump is located at the end of the aeration pipe furthest from the movable cover. This flotation cell changes the size of the bubbles by altering the length of the aeration pipe extending into the movable cover, thus changing the airflow at the bottom. The combination of porous media, the aeration pipe, the movable cover, and the aeration pump simulates the effect of a flotation column foamer, achieving micro-bubbles during bottom aeration, optimizing the flotation effect, and improving the flotation recovery rate of both oxide and sulfide ores. Bottom aeration allows large mineral particles to contact the bubbles, improving their floatability.

This utility model discloses a high-efficiency ore crushing and desliming system, including a raw ore stockpile, a heavy plate feeder, a jaw crusher, a four-layer linear vibrating screen, a first cone crusher, a single-layer vibrating screen, a second cone crusher, a second slurry tank, a second slurry pump, an intermediate stockpile, a ball mill, a first slurry tank, a first slurry pump, a first hydrocyclone, a third slurry tank, a third slurry pump, a second hydrocyclone, a thickener, and a fourth slurry pump. This utility model is designed for the development of high-mud ore in tropical rainforest regions. It can significantly improve the efficiency of ore crushing and conveying, enhance equipment uptime, and ultimately achieve the separate production of ore slime, which can be independently fed into a carbon leaching system. This improves the beneficiation indicators of high-mud gold ore and is of great significance for the efficient development of difficult-to-process high-mud ore in tropical rainforest regions. It also provides important reference for the crushing and development of similar ores.

The application discloses a stable and efficient inflatable mine flotation machine, which comprises a flotation column, a feeding mechanism, an inflation pump, a gas supplement mechanism, an aeration mechanism, a flow guide mechanism and a mixing mechanism. The feeding mechanism comprises a slurry pump and a mixing cylinder. The slurry pump is fixedly installed on the upper side of a mounting beam, and the mixing cylinder is fixedly installed on the middle part of the mounting beam. The slurry pump is in communication with the inside of the mixing cylinder and is used for realizing stable conveying and preliminary mixing of slurry. The gas supplement mechanism comprises a gas supplement pump, a gas distribution pipe and a gas distribution hole. A separate inflation pump primary gas supply structure and a gas supplement mechanism secondary gas supplement structure are arranged to form a multi-stage gas mixing system in cooperation with the internal mixing mechanism of the mixing cylinder. The inflation pump precisely supplies air through the inflation cover and the air inlet hole opposite the jet area of the slurry nozzle, and realizes primary negative pressure air mixing by using the high-speed jet negative pressure of the slurry. The gas supplement pump realizes circumferential uniform secondary air supplement in cooperation with the annular gas distribution pipe, the gas distribution hole and the gas guide cover, and avoids air floating and escaping.

This invention belongs to the field of mineral resource recycling technology, specifically disclosing a beneficiation method for recovering ultra-low-grade scheelite from molybdenum tailings. For refractory scheelite with severe alteration and mudding, the method employs pre-slurry conditioning, enhanced pretreatment with reagents moved forward, followed by grinding and classification of the raw ore. By combining collectors, the refractory scheelite is synergistically recovered, ultimately obtaining a tungsten concentrate with a grade >26%, achieving a comprehensive actual recovery rate of 77%. This invention's process achieves full recovery and utilization of refractory scheelite resources in tailings, while reducing the operating costs of refractory ore recovery, creating considerable economic and social benefits.

This invention discloses a copper slag modification and granulation system with real-time adjustable atmosphere and composition, comprising: a smelting furnace with an adjustable fume hood on top; an insulated chute for conveying the modified slag to the granulation section; a granulation device for dry centrifugal granulation of the modified slag; the adjustable fume hood having: an oxidizing gas interface for introducing oxidizing gas into the furnace; a reducing gas interface for introducing reducing gas into the furnace; a backup gas interface for introducing either oxidizing or reducing gas; an openable / closable observation / feeding port for observing the furnace state and / or adding modified materials to the furnace; and a flue gas outlet for discharging the flue gas generated in the furnace. This system integrates multiple gas interfaces and a feeding port on the adjustable fume hood of the smelting furnace, enabling active control of the slag's oxidation-reduction state and chemical composition during the slag holding stage, thereby optimizing the slag's properties and creating conditions for subsequent granulation processes.
