(1) Ore nature: The ore deposit is located in the middle and upper Carboniferous Huantian Group strata. The pot open group is divided into upper and lower parts: the lower part is limestone sandwiched dolomite and the white kinetic limestone; the upper part is thick dolomite. The mineralized dolomite is the ore layer, and its interlayer is gray dolomite, dolomitic limestone and limestone. The ore quality is mainly grade I and II, and its geological grade is shown in Table 1.

(2) Process flow: only the crushing and screening is set in the original design process, there is no washing, and the washing facilities are added in 1985. The process is two-stage crushing, one-time washing and one-tank washing machine washing. see picture 1. The main equipments produced are shown in Table 2. The quality of the products washed and not washed is shown in Table 3. The yield of each grade product and the sales rate of the products are shown in Table 4.

The ore mining is close to the geological grade, indicating that the ore body has less cracks and mud content, and the mining work is more thorough than the sandwiched waste rock and soil, ensuring product quality. Production process, the washing with the washing product quality without substantially close to the mine, such as SiO ₂ content difference of only 0.02 to 0.11%; in fine grade product quality difference is not great, reached a premium product or article 1 Quality Index. Mine the actual sales of the finished product rate reached 69.1 ~ 72.1%, less than about 30% of the finished product remaining ore content of MgO grain size of 20 ~ 0mm _{19.25 ~ 20.6%, SiO 2 0.13} ~ 0.33%, very good quality, is a premium product, Since the sale does not go out, the finished product is not counted. 1984-1985 has piled up about 90,000 t, not only the backlog and waste of resources and funds, but also increase the cost of production of finished ore sales for the full use of resources and enhance the economic efficiency of enterprises, in consultation with the user to adjust the product Granular structure and try to open up the market. The mine is not built to improve the quality of its products, but to improve the working conditions of workers. The dust-removing test results of the washing and non-washing plants are shown in Table 5. It can be seen that the dust content in the washing plant is reduced by 50~70%, which improves the working environment of workers and the same sieve hole is blocked. It is conducive to production operations, but the investment in additional mine washing facilities is about 600,000 yuan, and a small part of water and electricity consumption is increased, which increases the production cost accordingly.
