Xinjiang Salto Sea chrome ore is the only refractory grade chrome ore production base in China. The state has invested a lot of exploration funds by geologists thirty years of hard work, has proven reserves of ore group has 14, total proven reserves of millions of tons, Cr 2 O 3 content of more than 32% Rich ore accounts for about 50%.
The chrome ore of Xinjiang Nonferrous Metals Industry Co., Ltd. was put into operation in 1970. Starting from 1989, a local state-owned chrome ore and four township collective chrome ore were successively built and put into operation in the Salto Sea mining area. A total of 350,000 tons of chrome ore was produced from 1970 to 1991. It is mainly sold to Shanghai, Northeast and Luoyang refractory materials, and has contributed to the development of China's metallurgical industry.
The chrome ore is not only used as a refractory material, but also used to smelt stainless steel and various alloy steels to prepare various chromium salts.
China's chrome ore resources are in short supply, and it is necessary to spend a large amount of chrome ore imported each year. The price of chrome ore is relatively high, and the local mining of chrome ore is the way to get rid of poverty. The production of chrome ore in Xinjiang is developing rapidly, but there are also many problems to be solved.
First, the main problems
(1) Serious waste of resources
The Salto Sea chrome ore is in a complex state, lenticular, potato-like, chicken-like, and the mine is generally small. Some surrounding rocks are broken, which brings certain difficulties to mining.
Due to the weak technical strength of the local state-owned and township collective mines, poor management, some small ore bodies were discarded. The phenomenon of roofing ore mining has occurred. For example, a mine is under the management of a package. In the process of mining, the migrant workers have to pay more for their own profits and illegal operation, so that the exposed surface of the mining site exceeds the specified requirements, and the overfilling in the blasting process results in a large roof. More than 4,000 t-rich mines cannot be recycled underground.
(2) Since the chrome ore sales are looking for a way, the economic benefits are affected.
There is no unified management in the sales of chrome ore. All mining enterprises send people to run around, looking for sales channels and pressing each other. According to the relevant departments, if unified management, each ton of rich mines can sell 800 yuan, currently only sell 500 yuan, so that the economic benefits of mining enterprises are affected.
(3) Local state-run, township collective chrome ore deposits are urgently to be treated
Nonferrous Metals Industry Corporation has a simple chrome ore beneficiation plant to process iron ore fines, but low processing capacity, processing only 2 ~ 3t day. There are no concentrating plants in the five local state-owned and township collective chrome ore. The backlog of powder mines is over 10,000 tons. They once wanted to sell the powder mines to the non-ferrous metal industry company's concentrator. However, due to the low price, the backlog of powder mines has not been carried out so far. Mineral processing.
(4) Mining rich and abandoning poverty
Due to the lack of unified planning, no mining design and planning, and rich in eagerness, a certain mine reserves of 57,000 tons, rich ore only 17,000 tons. Has been harvested 14,000 tons, the current rich mine has been harvested. Because there is no concentrator, the remaining lean ore containing less than 25% Cr 2 O 3 is difficult to mine and requires closed pits. The discarding of low-grade chrome ore by other mining companies also exists.
Second, measures to strengthen the management and protection of chrome ore resources
(1) Establishing a unified management and coordination organization for chrome ore districts
Since 1989, there have been many mining enterprises with various economic components in the Salto Sea chrome ore district. Due to the low level of technology and management, there are problems such as serious waste of resources and mutual price reduction during sales. Therefore, the establishment of a unified management coordination mechanism for mining areas is in progress. It must be done. The non-ferrous metal industry company chrome ore has a history of more than 20 years of mineral exploration, strong technical force and high management level. Therefore, relying on the chrome ore of non-ferrous metal industry company, it helps local small mines in terms of technology and management, and solves some problems. Uniform organization of sales, unifying prices, and coordinating the relationship between mines will be more conducive to the development of chrome ore.
(2) Establishing a chrome ore dressing plant to improve the utilization of chrome ore resources
Stainless steel smelting, and the preparation of various kinds of steel used Bonanza chromium salts (or concentrate) Minimum Industrial index Cr 2 O 3 content of ≥32%, but a large amount of chromium ore Saertuohai fine ore in the mining process, and The higher the amount of ore Cr 2 O 3 , the more brittle the ore, the more the amount of fine ore, the annual production of fine ore in the whole mining area is about 5000t. All need to be mined before they can be sold. The low-grade chrome ore reserves in the Salto Sea mining area account for 50% and must be subjected to beneficiation to achieve industrial targets. In 1971, the Central Laboratory of the Bureau of Geology and Minerals conducted a beneficiation experiment on the borehole sample of No. 21 mine group. The content of Cr 2 O 3 was 22.80%, the content of concentrate Cr 2 O 3 was 32%, and the recovery rate of ore was 70%. After the beneficiation experiment, it is confirmed that the Salto Sea low-grade chrome ore is optional and economically reasonable. The establishment of a chrome ore dressing plant with a certain scale will help to improve resource utilization.
(3) Deeply publicizing and implementing the "Mineral Resources Law" to improve the cadre of mining areas, workers to run mines according to law, and the consciousness of scientific mining
In-depth publicity of the basic spirit of the "Mineral Resources Law", propaganda "mineral resources are owned by the state", "mineral resources are not renewable", "China's chrome ore resources shortage situation"; propaganda "very cherish, rational development and utilization and effective protection of mineral resources" The basic policy. Improve the consciousness of mining cadres and workers to conduct mines according to law and scientific mining.
(4) Strengthen technical training and improve the technical quality of cadres and workers
In view of the fact that local state-owned and township collective mining enterprises do not have mining professional and technical personnel, the vast majority of first-line mining workers are from the mainland, and technical training for cadres is very necessary. Bring into play the advantages of chrome ore technology of the non-ferrous metal industry company, combine the geological characteristics of the Salto Sea chrome ore mine, the status of the ore body, teach the knowledge of mining technology and management, train the cadres and workers in batches, and continuously improve the technical level and Management ability.
(V) Strengthen supervision and inspection of the exploitation and utilization of mineral resources of mining enterprises
The mining and mining departments at the prefecture and county level should often go deep into the mining area to supervise and inspect the exploitation and utilization of mineral resources of various mining enterprises. Those who seriously damage or lose mineral resources should be punished according to law. Resolutely stop the management method of escrow and management, require all mining enterprises to establish and improve relevant rules and regulations, and their main leading cadres bear full responsibility for rational development and utilization and protection of mineral resources, and formulate a system for cadres to take turns to work on duty, and personally guide production. Regulation and management of mining and management, and find problems in a timely manner.
(6) Strengthening the protection of the limited chromium resources in the Salto Sea
It is necessary to make overall plans, rationally allocate resources, and coordinate the development of central, local and township mines. To reflect the main status of the state-owned backbone mines. The chrome ore of Xinjiang Nonferrous Metals Industry Co., Ltd. has been built for more than 20 years. It has strong technical force, mining facilities, logistics and machine repair have been scaled, mining recovery rate is high, safety measures are good, and sufficient reserve resources must be reserved for the mine. Therefore, the local The mining scale of state-owned and township collective mining enterprises should maintain the status quo and no longer expand mining sites. For the development and utilization of limited chrome ore resources, the autonomous region non-ferrous metal industry company proposes a unified plan, rational layout, and is reported to the autonomous regional planning committee for approval of the competent department of the mine to achieve the purpose of rational development and utilization and effective protection of mineral resources.
The Salto Sea chrome ore district, led by the chrome ore of the non-ferrous metal industry company, assisted by the competent department of geology and mining, to strengthen the mining companies of various economic components, improve the technical level, strengthen management, unified sales, Salto Sea chrome ore Will achieve better economic, social and resource benefits.
