Example Embodiment

[0027] The invention concentrates the advantages of magnetic separation, flotation and electric separation processes, and recovers ilmenite from iron dressing tailings through the method of magnetic separation, flotation and electric separation.

[0028] Such as figure 1 Shown is the flow chart of the beneficiation method for recovering ilmenite from iron beneficiation tailings in Shandong area of ​​the present invention. The technical scheme of the present invention will be described in detail below with reference to the drawings and preferred embodiments.

[0029] Step 101: Dehydrate the iron dressing tailings;

[0030] The iron dressing tailings are transported to the titanium dressing plant with a pump. Usually, the water content in the iron tailings is high, and the iron dressing tailings need to be dehydrated first. At the same time, the iron dressing tailings accumulated in the tailing pond for many years can be recycled.

[0031] Step 102: Grind the iron dressing tailings, th...

Abstract

The invention discloses a benefication method for recovering ilmenite from iron tailings in the Shandong area. The method comprises the following steps of: performing ore grinding and high intensity magnetic separation on the iron tailings; floating the iron tailings which are subjected to high intensity magnetic separation; filtering the floated iron tailings to obtain titanium concentrate; and furthermore, electrically separating the filtered titanium concentrate. According to the method, ilmenite can be recovered from the iron tailings, TiO2 recovered from the iron tailings can be increased, the process flow is simple, the technology is reliable, and the content of TiO2 in the separated titanium concentrate is over 40 percent.

Description

technical field [0001] The invention relates to a beneficiation technology, in particular to a beneficiation method for recovering ilmenite from iron beneficiation tailings in Shandong area. Background technique [0002] The content of titanium is about 6 / 1000 of the mass of the earth's crust, and the world's reserves are about 3.4 billion tons. Titanium is distributed in ores, sand, clay, coal, petroleum, plants, and natural water. The world's titanium resources are dominated by ilmenite, which accounts for about 90% of the world's total titanium resources, and the reserves are mainly concentrated in China, Australia, South Africa, India and other countries; the remaining 10% comes from rutile, anatase, iron The reserves are mainly concentrated in Australia, South Africa, India, Brazil, Ukraine and the United States. [0003] Titanium concentrate is the raw material for producing titanium dioxide and titanium sponge. In 2010, the output of titanium dioxide in my country ...
