2) opening power is adjusted exciting curent; Open the Water filling valve of bucket, in the magnetic separation pipe, inject clear water by funnel;
3) behind the liquid level stabilizing, dip the experiment sample with beaker and slowly pour funnel into, access mine tailing with Plastic Drum simultaneously; After testing sample finishes, when liquid is no longer muddy in the magnetic separation pipe, stop to inject clear water; Emptying magnetic separation liquid in pipe is removed Plastic Drum then; Adjusting debris tube again by the height of adjusting the flexible pipe openend is that the magnetic separation pipe goes out open height, opens Water filling valve and adds clear water to the magnetic separation pipe, closes excitation power supply simultaneously, when liquid level surpasses two magnetic poles, stops to inject clear water, accesses the magnetic thing with beaker; Powered-down;
4) be placed on the beneath face of beaker cup with a strong magnet,, slowly pour out the water in the beaker when the complete post precipitation of magnetic thing;
5) the nonmagnetics liquid after the magnetic separation according to above-mentioned steps 2), 3), 4) step carries out sorting by the magnetic separation pipe again, in liquid, do not have till the magnetic thing;
6) whole magnetic things and the nonmagnetics that will collect precipitate respectively, filter, and put into the 105-110 ℃ of baking oven inner drying under the temperature, about 30 minutes of drying time of magnetic thing, coal slime dry about 2 hours of drying time, weigh after taking out cooling;
7) calculate: remove with magnetic thing amount and represent magnetic material content in the test specimen in the percentage of magnetic thing and nonmagnetics gross mass.
The computing formula of described magnetic material content is as follows:
γ
Magnetic=m
Magnetic/ (m
Magnetic+ m
Coal) * 100%;
In the formula: γ
Magnetic---magnetic material content, %; m
Magnetic---magnetisable material amount, g; m
Magnetic---nonmagnetics quality, g.
The invention has the beneficial effects as follows: do not need to liquid filter, oven dry and weighing dry-eye disease, carry out the assay of magnetic thing again after the dilution again.Reduce the measurement operation step, saved minute, can handle the mensuration of magnetic material content in the big quantity of fluid.
