The geological exploration work of barite ore in mineral exploration is divided into three stages: census, detailed investigation and exploration. The census stage: the purpose and task is to conduct a census of discovered mines and geological, geophysical and geochemical anomalies, and to find out whether there is any value for further work, submit a census report, and generally seek D+E-level reserves for detailed investigation. Stage work provides the basis. Detailed investigation stage: The purpose and task are to make an evaluation of whether or not there is industrial value for the deposits confirmed by the census stage work, and submit detailed investigation reports, generally seeking C+D reserves, of which C-level reserves are generally non- The metal mine is 20% to 50%, which provides a basis for whether or not to carry out the exploration stage work, and can provide the general plan for the mine and the proposal for the mine project. Exploration stage: The purpose and task are to explore the mineral deposits that have been confirmed by the detailed investigation stage and have been explored and utilized in the near future. According to the relevant regulations formulated by the National Mineral Reserves Committee, explore the reserves at all levels and submit the exploration report as a feasible mine construction. The basis for sexual research and design. The general requirements are: 1) Detailed exploration of geological and structural conditions in the exploration area 2) The shape and shape of the ore body (layer), the grade and structure of the ore, the type of industrial type, the type of grade and its proportion, etc., to achieve the corresponding reserves level and mine construction design. Claim 3) Research on the mineral processing performance of mineral processing, and whether it has an evaluation for industrial construction design. 4) Detailed exploration of hydrogeology, engineering geology and other mining technical conditions 5) Detailed technical and economic evaluation of the deposit. Types of exploration According to the geological exploration specifications for barite and toxic heavy stones issued by the State Bureau of Technical Supervision in 1992, the exploration types of barite deposits are divided into four categories: Type I: The ore body is large in scale, simple in shape, and simple in construction. Such as the Ankang stone ladder barite deposit in Shaanxi. Type II: The size of the ore body is large to medium, the shape is moderately complex, and the structure and the development of the vein are simple-medium, such as the Pancun barite deposit in Xiangzhou, Guangxi. Type III: The size of the ore body is mainly medium-sized, the shape of the ore body is complex, and the degree of structure and vein development is complex. For example, the Yongfang Lifang barite deposit III section of Yong'an, Fujian, and the Liuhe Bay section of Liuzhou, Suizhou, Hubei. Type IV: The scale is small, the shape is complex, and the structure is complex. For example, the Bingling Residual Barite Deposit in Bingling, Hainan Province. Most of the exploration methods for barite deposits use trenches, shallow wells, shafts and other projects to match core drilling. When the local shape is suitable, the exploration is carried out using flat rafts. Shallow wells can be used for exploration of residual sloped barite sand ore. The layout of the exploration project shall be determined according to factors such as the occurrence of the ore body. The barite ore body is generally layered and veined and can be arranged in the form of a survey line in order to obtain the profile data of the deposit and to ore the ore body in the horizontal and depth directions. When core drilling is carried out, the core core taking rate should not be lower than 70%. For deeper boreholes, the system should be tilted every 100m. In the tunnel, the barite ore is generally sampled by the groove method. For the dense block ore, the sample groove may be 10 cm × 3 cm or 5 cm × 10 cm. The sampling length is 0.5 to 2 m for layered ore and 0.25 to 1 m for veined ore. The loose ore can be sampled by stripping method, and the specification is 50-100 cm×20-50 cm. Drilling core sampling is generally done by the core method. The distance between the samples in the vein tunnel is generally 10-20 m. The sample should be placed so that the length of the sample is consistent with the thickness of the ore body. Various ore types should be sampled separately. The basic items of ore chemical analysis are BaO, SO3 and CO2, and other components such as Fe2O3, Al2O3, SiO2 and soluble salts can be determined by combined sample analysis. When studying a comprehensive ore, the content of PbO, ZnO, MnO, Au, Ag, and F must also be determined. In the case of ores containing sulfides, the combined samples should be subjected to full spectral analysis and chemical analysis to identify associated elements in the ore. Technical processing sampling generally uses the full lane method or the stripping method. Through the technical processing test, the quality and recovery rate of the mineral processing products should be ascertained, and the design data of the rational beneficiation process should also be obtained. The ore body is importantly determined by different types. The moisture should also be determined for loose ore. The barite used as a coating filler is measured by spectrophotometry to determine the color of the barite.
