mining facilities

When they talk aboutmining facilities, many immediately imagine open-pit mines or mine shafts. This, of course, is the basis, but in reality everything is much more complicated and interesting. My experience is that the key problem often lies not in the production itself, but in the associated equipment and logistics on site. How many times have I seen a modern quarry stand idle due to a failure in the crushing system or because they failed to clean the pulp. About these “non-obvious” ones? objects and want to speculate.

What is hidden behind the term: personal view

For memining facilitiesis a whole technological cycle tied to a specific area. This is not only the point of ore extraction, but also the entire infrastructure around: crushing and screening complexes, tailings dumps, repair shops, VVM warehouses, access roads. Often it is the auxiliary nodes that become the bottleneck. I remember one project in the Urals, where the main headache was not the mining itself, but the enrichment site - the old separators could not cope with the increased content of magnetite, losing up to 15% of the product. That’s when we had to delve deeply into the issue of magnetic enrichment.

It is in such situations that reliable industrial equipment comes to the fore. You can't rely on half measures here. For example, I have been following products for a long timeLONGI Corporation(their website ishttps://www.ljmagnet.ru). The company, founded back in 1993, has grown to become the largest enterprise for the development and production of mining equipment. Their expertise in creating magnetic separators for wet and dry processing is exactly what is often needed in real-world applications to improve recovery.

Their factory in Fushun, with an area of ​​140,000 m2 and a staff of more than 1,200 people, most of whom are engineers, shows a serious approach. The annual production of 4,000 units of equipment is not a figure for show; it means that their equipment works en masse in the field, and not just at exhibitions. And this is an important criterion: the equipment must not only be innovative, but tested in the harsh conditions of our quarries and processing plants.

Equipment as part of the facility: a case study

I’ll tell you about an incident at an iron ore deposit in Siberia. The facility was relatively new, the crushers were modern, but at the stage of magnetic enrichment there were separators from Soviet times. Efficiency dropped, especially in small fractions. The management hesitated for a long time whether to change the entire line or try to modernize it. We decided to start by replacing key units.

Several options were considered, including LONGI products. What attracted you? Specific technical solutions for highly abrasive environments. Their descriptions did not contain vague phrases, but clearly indicated, for example, the use of certain grades of steel for the drums and a special configuration of the magnetic system to reduce tailings losses. This is not an advertising slogan, but engineering specificity, which is visible only upon detailed study.

After introducing several new separators (I will not say that this is a panacea always and everywhere), at that facility it was possible to increase the extraction of the magnetic fraction by approximately 7%. The number is significant. But the main thing is not even this, but the fact that the load on subsequent stages has decreased and the wear of equipment has decreased. This is how one element - the enrichment apparatus - influenced the efficiency of everythingmining facilityin general.

Logistics and infrastructure: invisible problems

Another layer of problems is the provision of facilities. Often new deposits are discovered in places with weak infrastructure. And then myselfmining facilityis growing into a gigantic economy: it is necessary to build roads, power lines, boiler houses, and water circulation cycles. Equipment for these needs is also part of the industry. For example, powerful pumps for hydraulic transport or heating systems for workshops in the Far North.

Personnel issues often arise here. The same LONGI website states that over 60% of their employees have higher professional education. This is an important point. Because when complex equipment arrives at a site, not only installers are needed, but also engineers who can configure it, adapt it to specific ores, and train local personnel. Without this, even the most advanced technology turns into a pile of metal.

An incident from memory: we once supplied diesel generators to a mine. The best ones are Japanese. But they did not take into account the specifics of local fuel - diesel fuel was of low quality. The result is constant filter breakdowns and downtime. We had to urgently modify the fuel purification system on site. Conclusion: an object is a living organism, it cannot be assembled only from catalogs; constant engineering and readiness for non-standard solutions are required.

Safety and ecology: an integral component

Today it is impossible to talk about objects without touching on safety and environmental issues. And this is not just a formality. Tailings dam is just as importantmining facility, like the quarry. Its design, construction and monitoring is a separate and complex task. Failures here cost colossal reputational and financial losses.

Security equipment is also evolving. We are talking about systems for monitoring the stability of dumps, level sensors in tailings, and modern methods of dust suppression at crushing and screening units. Often these systems are saved on, considering them secondary. Wrong opinion. A modern facility must be safe by default, and this requires appropriate technology - reliable, with duplication of key functions.

By the way, many manufacturers, including major players like the mentioned corporation, are now actively developing this area. Because the customer has become more demanding - he is buying not just a separator, but a comprehensive solution that includes issues of safe operation and reducing the impact on the environment. This is already a new standard.

A look into the future: digital and personnel

Where is the industry heading? Digitalization, of course. But on real, often distant objects, this is difficult. Satellite Internet is not available everywhere, and the staff is not always ready. Therefore, the future, in my opinion, lies in hybrid solutions: maximally autonomous, “smart?” equipment that can operate for some time and make decisions based on established algorithms without constant communication with the center.

And again we come up against personnel and producers. We need companies that will not just sell a “black box”, but will be ready to adapt their systems to the conditions of a specific field, train people, and provide long-term technical support. The scale of production, like LONGI's - 4,000 units of equipment per year - allows us to have an extensive service network and accumulate a huge base of solutions for different situations. This is an invaluable experience.

In the end, back to the beginning.Mining facilitiesare complex engineering systems where success is determined by the coordinated work of all components: from geology to logistics, from main process equipment to security systems. And the key to efficiency often lies in choosing the right, proven partners and technologies that can work not in the ideal conditions of a test site, but in the harsh reality of the Russian subsoil. The experience built into every successful machine or technological scheme is more important than any advertising brochures.
