Iron Ore Beneficiation Process Overview

The iron ore beneficiation process typically involves crushing, grinding, magnetic separation, and dehydration. A well-designed production line ensures high-grade iron concentrate (60-67% Fe) with minimal waste. Key equipment includes jaw crushers, cone crushers, ball mills, and magnetic separators.

Core Equipment for Crushing & Sand Making

Equipment Model Example Key Parameters
Jaw Crusher PE-600×900 Feed opening: 600×900mm, Capacity: 50-160t/h
Cone Crusher HPT300 Max feed size: 230mm, Output: 120-400t/h
VSI Sand Maker VSI6X1263 Capacity: 200-650t/h, Rotor speed: 1000-1700rpm
Ball Mill MQY2740 Capacity: 15-28t/h, Rotation speed: 21r/min

Frequently Asked Questions (FAQ)

Q1: What’s the optimal feed size for iron ore beneficiation?
A: Typically below 25mm after primary crushing for efficient grinding.

Q2: How to reduce over-crushing in sand making?
A: Use multi-stage screening and adjust VSI rotor speed according to material hardness.

Engineering Case Study

Project: Magnetite beneficiation plant in Australia

Capacity: 1.2 million TPY

Solution: Three-stage crushing (Jaw + Cone + VSI) + two-stage ball milling + CTS1230 magnetic separator

Result: Iron recovery rate improved from 82% to 91%, concentrate grade reached 65.5% Fe.

Sustainability Considerations

Modern plants incorporate dry tailings discharge systems and water
