Traditional open-pit molybdenum mining methods, such as drilling-blasting, mechanical excavation, and truck transportation, face challenges in efficiency, safety, and environmental protection. To address these issues, the natural caving method has emerged as an innovative technology. By scientifically guiding the natural collapse of ore bodies, this method significantly improves mining efficiency, safety, and sustainability, offering a new direction for open-pit molybdenum mining.
Iron removal is a core step in kaolin purification. Current mainstream methods include physical, chemical, and microbial processes, with innovative technologies like superconducting magnetic separation significantly enhancing efficiency.
There are various types of tungsten deposits, including magmatic, sedimentary, metamorphic and hydrothermal types, and their formation is closely related to regional geological evolution. Ore often exists in the form of single mineral or symbiosis with other metals, and the microstructure directly affects the selection of ore dressing and smelting process.
In order to improve the efficiency of gold ore dressing and resource utilisation, a gold ore dressing plant adopts the combined process of ‘re-election + flotation, combined with centrifuge primary screening, shaking screen selection and other technologies, which significantly improves the recovery rate and product quality.
With the booming development of new energy industry, the demand for lithium resources is growing. As an important lithium-containing mineral resource, lithium mica produces a large amount of slag in the process of mining and utilisation. If these slags are not handled properly, they will not only cause environmental pollution, but also waste the valuable resources. Therefore, the resource utilisation of lithium mica waste residue has become the key to achieve a win-win situation in terms of environmental and economic benefits.
Before flotation, the quartz ore needs to be pre-treated. The Hanzhong quartz sandstone used in the experiment was first crushed and ground, and then screened out 109μm - 212μm particle size quartz sand as raw material. This size range of quartz sand is widely used, and the subsequent flotation purification study is of great significance to it.
The impurities in feldspar ore are various, and the harmful impurity elements are mainly iron and titanium, and the harmful impurity minerals include quartz, clay minerals, mica, rutile, etc. In the process of removing impurities, hand separation, washing and desliming are the common roughing methods.
Gold, as an important precious metal resource, its mining technology has always been a core topic in the field of mining. With the growth of global resource demand and the intensification of environmental protection pressure, the traditional gold mining method is facing serious challenges due to low efficiency, pollution and other problems. The introduction of modern mining technology not only significantly improves the efficiency and safety of gold mining, but also promotes the transformation of gold mining industry to sustainable development through green technology innovation.
Driven by the global wave of new energy, lithium, known as "white oil", has become the core raw material for power batteries and energy storage technology. As a key step in the efficient extraction of lithium from natural resources, lithium ore smelting technology directly affects the sustainable development of the new energy industry. At present, multiple lithium ore smelting processes, represented by lepidolite and spodumene, coexist.
Titanium, hailed as the "Metal of the 21st Century," is renowned for its high strength, lightweight, and corrosion resistance, making it indispensable in aerospace, chemical, and medical industries. Globally, titanium resources are primarily derived from ilmenite and rutile.
