Measurement method for volumetric weight of ore

Abstract

Belonging to the technical field of ore exploration, the invention discloses a measurement method for volumetric weight of ore. The method includes: firstly correcting a high precision electronic scale with a standard volumetric weight and a standard rock core sample, then measuring the weight of P1 of a dry ore sample in the air directly on the high precision electronic scale, and measuring the weight P2 of a wet ore sample in water by hanging the ore sample on the high precision electronic scale and then putting the ore sample into water for weighing, performing stress analysis to know that the ore is under the action of gravity and buoyancy in water, and carrying out calculation to obtain the volumetric weight of ore. The technical scheme provided by the invention reduces the tedious operation process of existing technological means, and calculates the volumetric weight of ore through direct measurement of weight of ore sample in the air and the weight in water. According to the technical scheme, testing of each sample can be completed within 5min, therefore the testing time of each sample can be greatly shortened, and the detection efficiency of the volumetric weight of ore is improved.

Description

technical field [0001] The invention belongs to the technical field of ore surveying, and in particular relates to a method for measuring the weight of ore. Background technique [0002] Ore weight is one of the main parameters in the calculation of mineral resources / reserves, so the determination of ore weight is of great significance to mineral geological exploration. According to the definition of ore weight, measuring ore weight needs to determine two parameters, one is the weight of the ore sample, and the other is the volume of the ore sample. According to these two parameters, the ore weight is obtained by dividing the weight of the ore sample by the volume of the ore. Usually the weight of the ore sample can be obtained by weighing directly, but the volume of the ore sample cannot be obtained directly, but can only be obtained by indirect methods. Therefore, how to measure the volume of the ore sample is the key point of ore weight measurement. [0003] There are f...

Problems solved by technology

[0010] However, this method has the following defects: (1) it is necessary to complete the wax coating on the ore in the field, which is cumbersome to operate, time-consuming and labor-intensive

[0011] (2) A special device for measuring displacement is required, which is difficult to complete in the field. It is often completed by sending the sample back to the laboratory, which is time-consuming and laborious.

[0012] (3) When draining water into the container, the volume reading of the water in the container is prone to error

[0040] However, this method has the following disadvantages: (1) It is necessary to wrap the sample in a thin plastic bag in the field, which is cumbersome, time-consuming and laborious.

[0041] (2) In order to make the test results accurate, the air in the thin plastic bag must be completely discharged, and the measurement error is large if the operation is improper.

[0042] (3) Whether the density of plastic bags of different materials is accurate will also affect the test results

[0050] However, this method has the following disadvantages: 1. The operation process is complicated, and the dry gauze needs to be constantly replaced during the measurement process, and the field test is time-consuming and laborious.

[0051] 2. Whether the gauze can completely absorb the discharged water will play a decisive role in accurately measuring the drainage volume, so improper operation will cause large errors
