Embodiment

[0036] A kind of equipment for analyzing the roasting effect of graphite-containing gold ore samples, such as Figure 1-Figure 11 As shown, it includes an angle adjustment unit, a sieving unit, a grinding unit, a base 1, a weighing instrument 2, a weighing plate 3, a lifting part 4 and a clamping block 5; a weighing instrument 2 is fixed on the upper side of the base 1; A weighing plate 3 is fixedly connected to the upper side of the weighing instrument 2; a lifting member 4 is fixedly connected to the rear side of the base 1; a clamping block 5 is fixedly connected to the front side of the lifting end of the lifting member 4; An angle adjustment unit is connected; the front side of the angle adjustment unit is connected with a screening unit; the upper side of the angle adjustment unit is connected with a grinding unit.

[0037] like Figure 1-Figure 6 As shown, the angle adjustment includes a first electric rotating shaft 101, a first mounting frame 102, a second electric r...

Embodiment 2

[0048] like Figure 1-Figure 13 As shown, this embodiment is further optimized on the basis of Embodiment 1, and also includes a fine sieve assembly, the sample dividing tube 203 is provided with a fine sieve assembly, and the fine sieve assembly includes an elastic sheet 401 and an annular plug 402; An elastic sheet 401 is fixed to the lower edge of the sample splitting tube 203 ; an annular plug 402 is fixed to the outer surface of the elastic sheet 401 .

[0049] After the operator puts the crucible 6 back on the weighing pan 3, the annular plugs 402 at the ends of the four elastic sheets 401 are buckled into the lower ends of the four sample dividing tubes 203 respectively, such as: Figure 13 shown, followed by completion as Figure 4 The change shown works, so that the crucible 6 is buckled upside down above the sample dividing plate 201. During the sliding process of the sample 7 along the sample dividing tube 203, the sample 7 needs to pass through the annular plug 40...

Abstract

The invention relates to the field of mineral analysis, in particular to a graphite-containing gold ore analysis method and sample roasting effect analysis equipment thereof. The technical problems that sample roasting is incomplete and a roasting method is not suitable when gold elements in ore in a mining area are accurately and reliably analyzed and detected are solved. The equipment for analyzing the roasting effect of the graphite-containing gold ore sample comprises an angle adjusting unit, a screening unit and the like, wherein the front side of the angle adjusting unit is connected with the screening unit. According to the graphite-containing gold ore analysis method and the sample roasting effect analysis equipment thereof, before the graphite-containing gold ore sample is roasted, the mixing effect of potassium nitrate and the sample is improved firstly, then the roasted sample is subjected to sieve leakage type weighing analysis work, characteristics which are difficult to distinguish by naked eyes are checked, and the sample roasting effect of the graphite-containing gold ore sample is analyzed. And finally, in combination with the subsequent treatment of the graphite-containing gold ore analysis method, the reinspection rate of the whole analysis work is reduced.

Description

technical field [0001] The invention relates to the field of mineral analysis, in particular to a method for analyzing graphite-bearing gold ore and a sample roasting effect analysis device. Background technique [0002] With the continuous improvement of the gold market in recent years, social customers' demand for carbonaceous rock mineral gold analysis has increased significantly. There are the following difficulties in the accurate and reliable analysis and detection of gold elements in ores in the mining area. First, the project has a large sample volume, tight time, heavy tasks, high requirements, and relatively lack of experience; second, due to the complex and diverse mineral types, carbonaceous There is no standard, no standard, and no unified process for graphite-containing samples, and the accuracy of gold element analysis is low, which affects the progress of the entire project and makes QC difficult. [0003] Regarding the difficulties existing in the above ana...
