After gravity separation of alluvial tin ore, tailings are not necessarily waste. However, a measurable tin content in shaking table tailings does not automatically mean that the material should be returned directly to the shaking table for reprocessing. The remaining tin may come from several different sources: coarse cassiterite particles still locked in gangue, liberated fine … Read more
Introduction Alluvial gold deposits are important sources of placer gold, but their processing can be challenging due to variations in ore composition, particle size distribution, clay content, and gold particle size. To achieve efficient gold recovery, a well-designed alluvial gold washing plant must combine effective ore washing, screening, gravity concentration, and concentrate upgrading. Our 400TPH … Read more
Tailings are the leftover materials from mining operations, often containing water and fine particles. Managing them safely and efficiently is crucial. How do mines transform these wet, messy slurries into stable, reusable materials? The answer lies in thickening and dewatering. The tailings thickening and dewatering process separates water from mineral solids, reducing volume and improving … Read more
Fluorite, also known as fluorspar, is a naturally occurring mineral composed primarily of calcium fluoride (CaF₂). It typically crystallizes in the cubic system and has a Mohs hardness of 4, perfect octahedral cleavage, and a wide range of colors, including purple, green, blue, yellow, and colorless. Owing to its relatively low hardness, distinctive optical properties, and … Read more
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
