gravity spiral concentrator working principlemar 26, · the humphreys spiral concentrator is a simple, efficient gravity concentrator which effects a separation between minerals of the proper size range that have sufficient difference in their specific gravity. this concentrator is a spiral conduit of modified semicircular crosssection, with outlets for removal of concentrate and middling.estimated reading time minshx and sc mineral spiral concentrators multotecsc mineral spiral concentrator features 6 different models and up to 3 different combinations; from 3 turns up to 8 turns; high medium or low grade profiles; materials of construction give long life, low cost and reduced maintenancespiral concentrator outotecoutotec spiral concentrators are used in most applications, particularly for concentrating lowgrade ores. manufactured from lightweight, corrosion and abrasionresistant materials, our spirals require minimal maintenance and upkeep. gives you an effective and lowcost solution for gravity separation. reduces maintenance with a durable design.
spiral (concentrators) an overview sciencedirect topics.5.3 spiral concentrator. the spiral concentrator first appeared as a production unit in 43 in the form of the humphrey spiral, for the separation of chromebearing sands in oregon. by the 50s, spirals were the standard primary wet gravity separation unit in the australian mineral sands industry.
