At a major gold mine project in Africa, traditional concrete construction stalled due to local resource scarcity. Implementing Xinhai's modular steel structure solution cut the project timeline by 40% and reduced overall costs by 30%. This is no isolated case—as the global mining industry shifts towards high-efficiency and low-carbon operations, steel structures have become the core choice for modern mineral processing plant construction.

A large chrome ore concentrator in South Africa originally had an annual processing capacity of 360,000 tons. Over time, the efficiency of the original gravity separation process declined, resulting in reduced capacity, low concentrate grades, and significant resource waste.

In this article, we will introduce the selection of gold mining methods, the underground mining process for gold deposits, and Xinhai’s advantages in gold mining services.

Placer gold mines have long been a hot spot for global mining investment due to their wide distribution, ease of extraction, and short investment return cycles. From the vast African continent to the resource-rich Asia-Pacific region, there is significant economic potential.

As a professional mineral processing service provider and equipment manufacturer, Xinhai Mining offers a complete range of services—from mining and process design to beneficiation plant construction, management, and operation. This article provides an in-depth look at the complete mica beneficiation process—from raw ore to final concentrate.

When the mineral processing plant is completed, the equipment starts operating normally, and concentrate is continuously produced—does that mean the project is truly successful? In fact, mine management (M) and operation (O) are the keys to sustained value creation.

​As international gold prices continue to rise, low-grade gold resources that were previously overlooked are being re-evaluated. Common gold extraction processes include flotation, cyanidation, and heap leaching, most of which require ores with a relatively high gold grade to be economically viable. For low-grade gold ores, typically with grades below 1 g/t, traditional processing methods often become uneconomical due to high costs.

The transformation and expansion of a concentrator is often far more complex than building a new one. This is due to challenges such as limited space, equipment compatibility, maintaining production continuity, and adapting to existing technical systems. With extensive experience in concentrator upgrades and expansions, Xinhai Mining Design Institute leverages modular design and dynamic construction planning to turn renovation challenges into opportunities for improving efficiency.
