Molybdenum Exploration

Among the 229 molybdenum mining areas identified in China, about 1/3 of them have been explored. geological exploration of molybdenum deposits is to provide necessary geological information for the design of mine construction in determining the scale of mine production, product program, mining and development program, overall layout of the mines and visionary planning of mine construction, as well as technical conditions of mining deposits such as hydrological geology and engineering geology, and the performance of ore processing and metallurgy, etc., therefore, it is the first step in the design of molybdenum deposits (areas) after census and detailed geological work, as well as the technical conditions of mining deposits such as geology, hydrological geology and engineering geology and the processing of ore. Molybdenum deposit (area) after census, detailed geological work, the geology of the deposit, hydrogeology and engineering geology of the mining technology conditions, as well as the technical performance of ore processing, comprehensive utilization, the external conditions of construction of the mining area to make a preliminary technical and economic evaluation is feasible, before the exploration work.

Exploration of molybdenum mining area, first of all, according to the size of the ore body, shape, thickness stability, tectonic damage and the degree of uniformity of the distribution of the main components of the ore to determine the type of exploration. Then according to the type of exploration to determine the means of exploration and exploration engineering spacing. 1983 Ministry of Geology and Mineral Resources and the Ministry of Metallurgical Industry formulated the "molybdenum geological exploration specification" will be the molybdenum deposits of the type of exploration is divided into four categories:
1) Exploration type Ⅰ: the ore body is huge in extension scale, simple in form, stable to relatively stable in thickness, with very little tectonic damage, and the main components of the ore are more evenly distributed. Deposits belonging to this type include Jinduicheng in Shaanxi and Sandaozhuang in Henan.
(2) Exploration type II: the extension scale of the ore body is mostly medium, the form is complex, the thickness is stable to unstable, the influence of tectonic damage and interspersed rock veins is small to large, and the distribution of the main components of the ores is uneven to very uneven. The deposits belonging to this type include Yangjiajianzi in Liaoning, Wudaoling in Heilongjiang, and Baoshan in Hunan.
3) Exploration type Ⅲ: the extended scale of the ore body is mostly large, the form is relatively simple, the thickness is relatively stable, the tectonic structure and rock vein damage is small, and the distribution of the main components of the ore is relatively uniform to non-uniform. Deposits belonging to this type include Shangfanggou in Henan Province.
4) The Ⅳ exploration type: the extension scale of the ore body is small to medium, the morphology of the ore body is complex to very complex, the thickness is unstable to very unstable, the impact of tectonic damage or rock veins interspersed is large to very large, and the distribution of the main components of the ore is very uneven to extremely uneven. Deposits belonging to this exploration type include Jilin Shirengou.
