V-Ti deposit hydrangea magnet Han River located deep in the northern edge of the fracture, genesis type is a deep portion of the magma yl shaped deposit. The main metal ore mineral ilmenite, magnetite, titanium, a small amount of pyrite, pyrrhotite, brass ore; gangue minerals pyroxene, plagioclase, hornblende, containing titanium Yuanmu, meteorite, etc. The ore contains TFe15.62%, TiO2 6.5%, S 0.33%, V2O5 0.14%, and Co 0.02%. Among them, iron and titanium are the main elements of this test. Cobalt is mainly present in pyrite and reaches a comprehensive recovery grade; vanadium exists in the ilmenite and titanomagnetite in the same form as the isomorphism. The principle process used in this test is: flotation-magnetic separation-re-election combined process. Firstly, cobalt and sulfur are floated to obtain qualified cobalt-sulfur concentrate; flotation tailings are obtained by a coarse-wet weak-weak magnetic separation to obtain vanadium-iron concentrate; magnetic separation tailings are re-elected (shaker) to select ferrotitanium The mine uses three kinds of process schemes to obtain titanium concentrates for comparison. The main technical indicators of the test are: cobalt-sulfur concentrate: yield 1.01%, sulfur grade 24.98%, sulfur recovery rate 84.7%; cobalt grade 0.23%, cobalt recovery rate 11.53%; vanadium iron concentrate: yield 9.77%, iron grade 56.0%, iron recovery rate of 34.43%, vanadium grade 0.51%, and hydrazine recovery rate of 34.44%. The yield of titanium concentrate obtained by the magnetic tail grade shaker process scheme is 14.67%, the grade of titanium dioxide is 16.17%, and the recovery rate of titanium is 38.24%. The yield of titanium concentrate obtained by the magnetic tail regrind non-grading shaker process scheme was 7.27%, the titanium grade was 23.6%, and the titanium recovery rate was 26.94%. The yield of titanium concentrate obtained by the magnetic tail non-grading direct shaker process scheme is 13.48%, the grade of titanium dioxide is 15.0%, and the recovery rate of titanium is 29.11%. Under the condition of grinding fineness of 70%-200 mesh, wet weak magnetic separation and magnetic separation tailings were re-elected. The iron concentrate obtained by the experiment was investigated to contain 42.89% iron, 25.83% TiO2, and the iron content was 51.94. %, titanium concentrate containing 37.8% of titanium, the recovery rate of titanium is 22%. The anchor drilling rig is mainly used in hydro power stations, railways and highways, in order to prevent and control various geological disasters, anchoring operations are carried out on landslides and dangerous rock masses.It is mainly used in landslide and dangerous rock anchoring projects in tunnels, railways, highway slopes and other kinds of geology, especially for high slope rock anchoring projects. Drilling operations consume less manpower and material resources, have high construction efficiency and high safety factor. It is also suitable for the construction of deep foundation pit support, reinforcement hole for anti-float anchor and foundation grouting, blast-hole in blasting project, high pressure sprinkling stake and tunnel pipe support hole, etc..

The drilling technology with casing of anchor drilling rig is designed to solve the problem that complex rock layers cannot be holed. The drill bit impacts rock continuously, and the broken rock is blown to the ground by the air pressure discharged from the gap between the casing and the drill pipe. The drill pipe and bit can be lifted after punching the hole, and the casing is placed in the middle of the rock layer, so that the rock layer doesn't collapse.
