Before a mineral processing plant goes into production, it conducts a laboratory mineral processing test. But why might the concentrate grade and recovery be so impressive in the lab, yet fall short of expectations once the project is operational? This is precisely the "amplification effect" of mineral processing technology. To mitigate this risk, it is recommended to conduct a pilot-scale mineral processing test after the laboratory test but before the project launch. This scientific simulation compensates for the limitations of lab-scale tests and provides precise guidance for industrial production.

Molybdenum plays a key role in high-strength alloys, corrosion-resistant materials, electronic components, catalysts, and other fields. However, molybdenum occurs in low and dispersed concentrations in the Earth's crust, primarily in the form of molybdenite. Extracting molybdenum from molybdenite requires a scientific and precise beneficiation process. Xinhai Mining, with over 30 years of experience in the mineral processing industry, has conducted extensive research on molybdenum beneficiation and has rich experience in EPC project execution.

Tungsten concentrate prices continued to climb in the first half of 2025. By the end of July, the price of 65% wolframite concentrate had risen by over 34% compared to the beginning of the year. With surging demand for tungsten in new energy and high-end manufacturing industries, tungsten mining investment has entered a golden window of opportunity.

Nickel is a key raw material for the production of stainless steel and an essential component of lithium battery cathode materials. With the growing popularity of new energy vehicles, market demand for nickel continues to rise, and investment in nickel processing plants holds great potential.

Mine general contracting is a "turnkey" engineering model in which a single contractor is responsible for the entire mining project. The contractor is responsible for the full process from design to commissioning (EPC). By integrating resources, optimizing the process flow, and transferring risks, the owner is provided with a mine that is delivered on time, within budget, and meets performance requirements. This model places high demands on the contractor's technical strength, project management, and risk-bearing capacity.

This article introduces the four commonly used processes for gold tailings reprocessing, as well as the procedures and steps involved in the reprocessing workflow.

With 28 years of experience in the mineral processing industry, Xinhai Mining has broken through technical bottlenecks and laid a solid foundation for improving the efficiency of the beneficiation plant and the value of mineral resources. This article explains the technical difficulties of hematite flotation and Xinhai's solutions, and shares successful cases.

Dolomite has a wide range of uses and is widely applied in ceramics, glass, chemicals, metallurgy, environmental protection, and other fields. Natural dolomite ore usually contains impurities such as quartz, calcite, iron-bearing minerals, silicates, and clay minerals. The presence of these impurities directly affects the purity and downstream application performance of dolomite. Therefore, it is very important to remove impurities and improve purity.This article introduces the key equipment and process flow of dolomite processing.
