How to Handle Sand Production from Iron Tailings

With the continuous tightening of regulations on sand and gravel resources, comprehensive utilization and mine ecological restoration have become key industry focus areas over the past two years. Given the non-renewable nature of mineral resources, the effective use of is urgent. Can iron ore be processed into sand? How should one approach sand production from iron ?

1. Can iron be used to produce sand?

Recently, several clients have successfully launched sand-making projects. By using raw materials such as iron ore , granite , and coal gangue for aggregate production, it has been demonstrated that these processes can yield recycled aggregates in various specifications. Furthermore, tests on hardness, density, gradation, and other indices confirm that the resulting material is suitable for applications including concrete preparation, pavement base laying, and the firing of recycled bricks.

2. What is the process for producing sand from iron , and what equipment is required?

Iron ore typically possess high hardness. To effectively produce sand, a combination of cone crushers and vertical shaft impact (VSI) sand-making machines is generally required. The specific details are outlined below.

1) Single-stage crushing: Single-cylinder cone crusher

Production capacity: 36-2181t/h

Discharge granularity: 6-41mm

The single-cylinder hydraulic cone crusher integrates mechanical, hydraulic, electrical, automation, and intelligent control technologies. It is widely applicable for medium, fine, and ultra-fine crushing operations in metal and non-metallic mines, cement production, sand and gravel processing, metallurgy, and other industries. This equipment offers high crushing efficiency, low operational costs, convenient maintenance and adjustment, and superior product particle size distribution.

2) Two-stage sand making: Impact sand making machine

Production capacity: 40-650t/h

Discharge granularity: 0-5mm

Our stationary lineup includes the , high-capacity , low-capacity roller-type, and fine crushers. However, our specialized impact is engineered for large-scale operations with processing capacities ranging from 10 to 500 tons/hour, reducing the production cost per ton of finished sand to just 60% (3/5) of conventional lines. Designed specifically for mine tailings, this machine features integrated shaping capabilities that produce excellent cubic particles compliant with national standards. With its high degree of automation, low energy consumption, and high crushing ratio, it offers a rapid return on investment, typically recovering costs within 4–5 months.
