Embodiment 1

[0033] Embodiment 1: The combined mineral processing process: the raw ore and the medicament are stirred to form a slurry feed, after roughing by a rougher flotation column, two times of selection by a selection flotation column, and a pair of scavenging flotation machines and scavenging flotation columns The rougher tailings are swept multiple times, and the fine sweep flotation machine sweeps the fine I flotation column tailings to obtain the final concentrate and tailings;

[0034] Specific steps are as follows:

[0035] (1) According to the requirements of mineral types and sorting operations, add chemicals and raw ore F in the slurry mixing tank to mix and mix; the mass percentage concentration of the input material formed by stirring and mixing is 25%-45% according to the different types of selected minerals;

[0036] (2) The ore pulp formed by stirring flows into the rougher flotation column for roughing, and the rougher tailings are fed into the Sweep I flotation machi...

Abstract

The invention discloses a co-platform flotation column and flotation machine combined separating technology and device and belongs to mineral separation technologies and devices. The technology comprises the steps that raw ore and reagents are stirred to form ore pulp feeding, and by roughing through a roughing flotation column, two-time concentration through a concentration flotation column, multi-time scavenging on rougher tailings through a scavenging flotation machine and a scavenging flotation column and scavenging on refining I flotation column tailings through a fine scavenging flotation machine, final concentrate and tailings are obtained; at the same platform, the flotation column and the flotation machine combined separating technology is used for processing metal ore, the flotation columns are used in the roughing and concentration processes, the processing amount is large, separation accuracy is high, finally, high-grade concentrate products can be obtained, the flotation machine and the scavenging flotation column are used for carrying out multi-time scavenging on the roughing flotation column tailings, concentrate products in the tailings can be recycled to the maximum degree, refining I flotation column concentrate tailings are subjected to fine scavenging, the maximum recovery rate of the concentrate products is guaranteed, enterprise economy benefit is improved, the system technology is simple, consumed electricity is low, occupied space is small, and operation cost is low.

Description

technical field [0001] The invention relates to a mineral processing technology and device, in particular to a combined mineral processing technology and device with a platform flotation column and a flotation machine. Background technique [0002] Metal and its alloy materials are widely used in economic fields such as electronics industry, machine manufacturing, military industry, agriculture, etc. Metal resources have extremely important strategic significance to my country's economy. With the rapid development of my country's economy, the demand for metal minerals According to incomplete statistics, the consumption of important mineral resources accounts for 20%-48% of the total global consumption. Metal minerals have become indispensable basic materials and strategic resources in modern industry, agriculture, national defense engineering and even new technology fields. [0003] Although my country has abundant reserves of mineral resources, the amount of available high-g...
