Jig separation is a gravity concentration process that relies on the repeated loosening, settling, and consolidation of a material bed. The performance of a jig separator is therefore determined not simply by whether the machine is operating, but by whether the bed can develop stable and effective density stratification. For different feed materials, jigging parameters such … Read more
Introduction Placer tin ore is commonly processed by gravity separation methods such as sluice boxes, jigs, and shaking tables because cassiterite has a relatively high density compared with many associated gangue minerals. However, even after gravity concentration, the resulting placer tin ore concentrate may still contain excessive iron, which can affect concentrate quality, downstream processing, … Read more
Introduction Gabon is increasingly attracting attention for its potential in critical and strategic minerals, including niobium, tantalum, rare earth elements, manganese, and other technology metals. Among these resources, the Mabounié deposit is particularly notable. Located in the Moyen-Ogooué province near Lambaréné, Mabounié is a polymetallic deposit containing niobium, tantalum, rare earth elements (REE), phosphate, scandium, and … Read more
Placer gold deposits are secondary deposits formed when primary gold ores or gold-bearing geological bodies undergo weathering, erosion, and transport, followed by mechanical deposition and enrichment in rivers or specific landforms. Because placer deposits occur in a wide range of geological and geographical conditions, there is no single processing plant configuration that fits every project. … Read more
Introduction As the global new energy industry experiences explosive growth, the Democratic Republic of Congo (DRC), known as the “Cobalt Kingdom,” has become increasingly strategic. According to data from the International Copper Study Group (ICSG), in 2023, the DRC contributed 74% of global cobalt production and 11% of copper supply. However, the six-month rainy season (October to April) brings severe ore … Read more
Abstract This study investigates the application of a novel fine-grain gravity separator in the copper-lead separation process for a low-grade copper-lead-zinc polymetallic ore from Inner Mongolia. The traditional mixed flotation-separation process faced challenges such as unstable indicators, high reagent costs, and water scarcity. By introducing a new gravity pre-concentration step, the process achieved significant improvements … Read more
Introduction: China’s Premium Iron Source Skarn iron deposits represent one of China’s most valuable iron resources, accounting for approximately 10% of national reserves but contributing nearly half of the country’s high-grade iron ore. These deposits are a type of high-grade iron ore formed through hydrothermal metasomatism at the contact zones between intrusive igneous rocks (e.g., granitoids) and carbonate rocks (limestone, dolomite). They … Read more
Heavy rain can seriously disrupt your hydrocyclone operations. Suddenly thin slurry, unstable feed pressure, and overflowing cyclones become common problems. I’ve seen many mines lose thousands in recovery rates by not adjusting their hydrocyclones properly before storms. For rainy conditions, lower your hydrocyclone overflow first to handle thinner slurry. Then adjust spigot diameter to maintain … Read more
When the overflow from a thickener suddenly becomes turbid, it’s a problem that causes headaches for many mineral processing plants. You may have already tried adding flocculants, but the results have been inconclusive. The real cause may lie in details you haven’t noticed. The root cause of turbid overflow in a thickener is an unstable … Read more
Introduction: The Backbone of Global Copper Supply Porphyry copper deposits dominate global copper production, accounting for over 60% of the world’s Cu resources. These geologic giants combine accessibility with metallurgical efficiency, making them prime targets for modern mining operations. Understanding their formation, distribution, and peculiarities offers a masterclass in economic geology while guiding exploration strategies … Read more
