Most foundries do not have the very expensive equipment to remove the burned out clay and substitute new clay, so instead, those that pour iron typically work with silica sand that is inexpensive compared to the other sands. As the clay is burned out, newly mixed sand is added and some of the old sand is discarded or recycled into other uses.
Iron removal equipment is necessary. If the customer has high requirements on the purity of silica sand, pickling equipment can be added according to the needs of the customer, which can improve the grade of silica sand. The purity of silica sand is usually improved by using strong iron remover combined with pickling.
Below is the flowsheet of silica sand magnetic separation system. For more information about quartz sand extracting and iron removal, please visit SINONINE website:,or contact us directly by +86-（WhatsApp）.
