Embodiment Construction

[0020] The technical solutions of the present invention will be described below in conjunction with the accompanying drawings and implementation methods.

[0021] like figure 1 Shown, a kind of preparation method of granular primary ore light sheet, comprises the following steps:

[0022] a. Crushing: Use a jaw crusher to crush the raw ore to a granular ore sample with a particle size of -3mm, and shrink it to 100g after mixing;

[0023] b. Adhesive melting tablet: Weigh the mineral sample in step a and mix it with the binder in a ratio of 2:1, stir evenly and heat to 80°C, then pour the mixture into the sample mounting machine and pressurize to 2.5MPa and stop About 40s, take out the cured light sheet grinding blank;

[0024] c. Grinding sheet: place the light sheet grinding blank in step b on the sample grinding machine for rough grinding, use 120# water-resistant sandpaper for rough grinding, and rinse it with clean water after grinding for 1 minute;

[0025] Put the rou...

Abstract

The invention provides a preparation method of a granular primary ore polished section, which comprises the following steps: crushing primary ore into granular ore samples with the granularity of -3mm, uniformly mixing the granular ore samples with a binding agent, uniformly stirring the granular ore samples and the binding agent to form polished section grinding blanks through the operation of a mounting press, and performing coarse grinding, medium grinding and fine grinding on the polished section grinding blanks through a sample grinding machine, subjecting the polished section grinding blanks to polishing solution polishing and water polishing, and finally putting the polished section grinding blanks into an ultrasonic cleaner to be cleaned and dried. Combustion and poisonous and harmful gas release are not prone to occurring in the section preparation process, the environment-friendly and safe effects are achieved, meanwhile, the sample preparation time can be greatly shortened, the situation that coarse and fine particles are not evenly distributed is avoided, and the section grinding efficiency and the section polishing quality are improved.

Description

technical field [0001] The invention belongs to the technical field of mining products, and relates to a method for preparing granular primary ore light sheets. Background technique [0002] The primary ore needs to observe the microstructure and composition under a polarizing microscope. Therefore, it is necessary to crush a representative ore to a suitable particle size to prepare a light sheet, which is used to formulate and guide the separation and enrichment plan of useful minerals. In the past, the light sheet preparation method is to crush the ore to -3mm, add a curing agent in proportion to the epoxy resin and heat it at a high temperature until it softens, add granular ore and stir well, then put it in an oven and heat it at a constant temperature for 6-10 hours until The epoxy resin is completely cured, and the grinding machine uses emery as the abrasive for rough grinding-medium grinding-fine grinding-polishing, and finally makes an observable light sheet. The sho...
