Problems solved by technology
Increased costs due to increased transportation costs due to the large number of boron mines located in remote, inaccessible areas
Generally, people will carry out preliminary processing of ore, and then transport the processed boric acid out, which saves transportation costs, but on-site processing requires a lot of auxiliary materials, and these auxiliary materials also need to be transported from the outside, and the ore sites are distributed in uninhabited areas. In the deserted Gobi and grasslands, there is a lack of water and electricity, so the processing cost is very high

Embodiment Construction
[0012] The present invention is a kind of purification technology of boron-containing ore, comprises the following steps:
[0013] (1) The ore to be purified is first dried and pulverized;
[0014] (2) Remove the magnetic substance in the crushed ore;
[0015] (3) The ore is heated to 800-850°C, heated and kept for calcination, and the calcination time is 40 minutes;
[0016] (4) Cool the heated ore, and remove the magnetic substance again.
[0017] The invention provides a purification process of boron-containing ore, which further purifies the ore, the purification method is simple, and the cost is low, and the sulfate, carbonate, moisture, crystal water, organic matter, etc. in the raw ore are removed without various auxiliary materials, The utilization value of the ore is improved and the transportation cost is reduced.

The invention provides a purification process of boron-containing ores. The purification process is used for further purification of the ore and has the advantages that the simple and low-cost effects are achieved, sulfates, carbonates, water, crystal water and organic matters and the like in raw ores can be removed without need of various auxiliary materials, so that the utilization value of the ores is improved and the transportation cost is reduced.
Description
technical field [0001] The invention relates to a purification process of boron-containing ore. Background technique [0002] Boron ore is a precious mineral deposit, and more than 90% of the high-grade boron-magnesium ore resources in my country are distributed in Tibet and Qinghai. Because a large number of boron mines are located in remote and inaccessible areas, the transportation fee increases, thereby increasing the cost. Generally, people will carry out preliminary processing of ore, and then transport the processed boric acid out, which saves transportation costs, but on-site processing requires a lot of auxiliary materials, and these auxiliary materials also need to be transported from outside, and the ore sites are distributed in uninhabited areas. It is located in the deserted Gobi and grasslands, where there is a lack of water and electricity, so the processing cost is very high. Contents of the invention [0003] The purpose of the invention is to overcome t...
