Problems solved by technology

1. Recovering valuable metals such as iron, titanium, sulfur and cobalt from the tailings of Panxi vanadium-titanium magnetite has achieved good results; however, limited by technological progress and development, the current status is difficult to obtain The leap and development; and in recent years, the attention to the rare and precious metals such as scandium, gallium, indium and other elements contained in it, the process is complicated in the short term, and it is difficult to promote the actual production and recycling
2. Use Panzhihua tailings to prepare extensive building materials such as building bricks, and partially prepare cement, glass-ceramic and (dark) ceramic products. Although the construction industry uses a large amount of tailings to process, the economic value of its products Low, small radiation radius, limited market capacity, difficult to promote recycling for a long time
However, there are no research reports at home and abroad on the recovery of non-metallic feldspar minerals from the vanadium-titanium magnetite tailings of basic ultrabasic rocks rich in iron and titanium.

Embodiment 1

[0032] Sorting feldspar (type) concentrate and its separation method from vanadium-titanium magnetite tailings, comprising the following steps:

[0033] (1) Use a 0.6mm sieve to separate the vanadium-titanium magnetite beneficiation tailings, and remove the part above +0.6mm;

[0034] (2) The -0.6mm material obtained in step (1) is adjusted to PH value with sulfuric acid, xanthate is used as collector, 2 # Oil is used as a foaming agent to remove sulfides (pyrite, chalcopyrite, etc.) in tailings by flotation (sulfur-cobalt concentrate can be obtained through beneficiation);

[0035] (3) Use weak magnetic separation to remove the desulfurized tailings obtained in step (2) at a magnetic field strength of 0.28T to remove the strong magnetic minerals in the tailings (titanium magnetite and its altered minerals, which are poor and rich conjoint organisms) ); the beneficiation tailings usually contain some (poor and rich) joints of strong magnetic minerals and gangue minerals, and ...

Abstract

The invention relates to feldspar concentrates separated from vanadium titano-magnetite tailings and a separation method thereof. The vanadium titano-magnetite tailings are used as raw materials; firstly, impurities in the vanadium titano-magnetite tailings are separated; then, sulfides in the tailings are removed through flotation; strongly magnetic minerals in the tailings are removed through low-intensity magnetic separation; weakly magnetic minerals in the tailings are removed through high-intensity magnetic separation; and finally, the feldspar concentrates can be obtained through classification or reverse flotation. The core problems of high quantity, limited transportation radius and low economical value of the vanadium titano-magnetite tailings are overcome; and the environmental pollution and the safety problem caused by long-time accumulation of the tailings are solved.

Description

technical field [0001] The invention relates to sorting feldspar (type) concentrates from vanadium-titanium magnetite tailings and its separation method, especially from vanadium-titanium magnetite tailings in basic ultrabasic rock mass rich in iron and titanium Sorting feldspar concentrate and its separation method. Background technique [0002] Vanadium-titanium magnetite is a mineral resource widely distributed in the world, mainly distributed in China, South Africa, Russia, Canada, the United States, India and other countries. [0003] my country's vanadium-titanium magnetite is mainly distributed in Panzhihua-Xichang area, Chengde-Liaoxi area, Xinjiang and North Daba Mountain Qinling and other areas. Among them, the Panxi area has reserves of more than 10 billion tons and is the largest vanadium-titanium magnetite deposit in my country. [0004] In the iron dressing tailings of the vanadium-titanium magnetite resources concentrated mining area in Panxi area, ilmenite ...
