In the field of precision wet screening of silica sand, traditional metal screen mesh severely restricts production efficiency due to frequent replacement, metal fatigue fracture, and efficiency degradation. This article is based on USGS 2023 data and reveals how the top 5 countries in global silica sand production (the United States, China, Italy, Germany, Australia) and top mining companies (such as Sibelco, Covia) optimize production through polyurethane sieve plates.

Zijin Mining's core asset, Kamoa-Kakula, Africa's largest copper mine, suffered a sudden well flooding accident, resulting in a sharp reduction in the planned copper production in 2025 from 520,000-580,000 tons to 370,000-420,000 tons. The accident was caused by the damage of underground pumping facilities caused by multiple mine earthquakes in late May, and groundwater flooded the mining surface in the eastern area. At present, the western area has gradually resumed production, and the company is urgently installing high-power water pumps to drain water, and it is expected to be fully restored in August 2025.

This production reduction will reduce Zijin Mining's equity copper production by 44,000-93,000 tons, directly impacting its annual target of 1.15 million tons of mineral copper. As the largest source of incremental production in the original plan (expected to increase production by 143,000 tons), Kamoa's production reduction forced the company to launch an emergency plan: using the resumption of production in the western area, deploying 3.8 million tons of surface stockpiled ore (grade 3.2%), and developing high-grade mining sections. Although the third phase of the concentrator was not affected, it remains unclear whether the full-year target can be achieved.

The latest ranking of global mining companies released by an international authority shows that the industry is undergoing a structural adjustment. BHP Billiton (BHP) with a market capitalization of $126 billion and diversified resource reserves has been the top of the list, while Rio Tinto (Rio Tinto) with a market capitalization of $103 billion stays in the second place. China's mining companies have performed brilliantly: China Shenhua ranked third in the world with a market capitalization of more than 820 billion yuan, and Zijin Mining jumped to the fifth place, becoming the only Chinese company to enter the top five in the global metal mining industry, with its copper and gold production and lithium resources layout highlighting its strategic ambitions.

The rankings, which combine market capitalization, production, resource reserves and sustainability, reveal three major trends: 1) Chinese companies are accelerating the layout of new energy metals based on their traditional energy advantages; 2) green mines and energy saving and emission reduction have become core competitiveness; and 3) geopolitics and market fluctuations are forcing the industry to innovate its strategies. This article analyzes the key data of headline companies and the direction of industry change.

Whether you're involved in exploration, extraction, processing, or sustainability, this event is a must-attend for professionals looking to stay ahead in the evolving mining sector.

As key components of industrial screening, the performance differences between Rubber Screen Panels and polyurethane screen plates directly affect screening efficiency and equipment life. This article systematically compares the core characteristics of the two from the dimensions of material structure, wear resistance, impact resistance, weather resistance, screening accuracy, etc., and combines the actual needs of different industry scenarios (such as coal preparation plants and metal mines) to deeply analyze procurement costs, maintenance difficulties and long-term economic benefits. Through specific cases (such as raw coal screening in coal mines and wet ore processing in gold mines), scientific selection strategies are provided to help users select the optimal screen plate solution based on material hardness, corrosiveness, humidity and other parameters to achieve a balance between production efficiency and cost control.

This report deeply analyzes the core dynamics of the global coal market: consumption will reach 8.77 billion tons in 2024 (+1% year-on-year), and demand in emerging markets and developed economies will be severely differentiated - India's consumption will soar by 6% (an increase of 70 million tons), China will grow steadily by 1.1%, and the EU will drop sharply by 12%. Asia dominates global supply, with Indonesia exporting 560 million tons of thermal coal. Prices fluctuate violently: thermal coal will soar to US$407.5/ton in 2022 and is expected to fall back to US$130/ton in 2025; coking coal may rise slightly to US$210/ton. The report reveals three major risk variables: China's electricity demand resilience, accelerated renewable energy substitution, and the release of new coal mine capacity, providing key references for energy decision makers.

Polyurethane screen panel is a highly elastic, wear-resistant, and impact resistant screening component widely used in screening, dewatering, and grading operations of materials such as coal, iron ore, and copper ore. Compared with traditional metal screen panels, polyurethane screen panels have the advantages of low noise, long service life, and low maintenance costs. This article provides a detailed introduction to the three installation methods of polyurethane screen panels (bolt fixation, track seat connection, hook connection), as well as their technical parameters (aperture, thickness, hardness, etc.) and customized services, to help users choose the most suitable screening solution.

The Trump administration has greenlit Signal Peak Energy’s coal mine expansion, accelerating exports to Japan and South Korea under an energy emergency directive. This move, praised for strengthening U.S. alliances, faced fierce opposition from environmental groups over climate risks. Meanwhile, global energy investments are set to reach a record $3.3 trillion in 2025, with China leading clean energy spending. Despite declining coal trade volumes—Indonesia’s exports dropped 10.9%—Germany’s lignite production rose 5.9%, reflecting ongoing fossil fuel reliance. The debate highlights tensions between energy security and environmental sustainability as nations navigate shifting energy policies.
