Iron Ore Processing Line

Iron Ore Processing Line

Iron ore beneficiation processing lines are core systems for purifying and upgrading iron ore to meet the standards of the steel smelting industry. Commonly used industrial iron ores are mainly classified into magnetite, hematite, and limonite, with significant differences in ore grade. Guote Equipment has developed professional and mature beneficiation line solutions for different ore types and grades, efficiently producing high-quality iron concentrate.

Guote iron ore beneficiation processing lines boast superior performance and strong adaptability. The lines employ unique processes to effectively improve the recovery rate of low-grade and complex symbiotic ores. Based on modular design, they can flexibly combine magnetic separation, gravity separation, and other processes for different iron ores, precisely adapting to ore condition requirements. The entire line is equipped with an intelligent automatic control system and comprehensive environmental protection facilities, ensuring stable operation and a high degree of automation, achieving efficient, green, and clean beneficiation operations.

PROCESS DESCRIPTION

01

Multi-stage Crushing

The raw ore is fed into the crushing system by loaders and excavators, and then evenly distributed by a vibrating feeder. The material undergoes primary crushing in a jaw crusher, secondary crushing in a single-cylinder hydraulic cone crusher, and fine crushing in a multi-cylinder hydraulic cone crusher. Combined with closed-circuit screening via a vibrating screen, the discharge particle size is strictly controlled to ensure that qualified ore is steadily fed into the grinding circuit.
02

Closed-circuit Grinding and Classification

The crushed 0–12mm ore particles are fed into a ball mill for grinding, and the ground material is classified by screening equipment. Oversized particles are returned to the ball mill for regrinding, while the qualified slurry proceeds to the beneficiation stage, achieving stable and highly efficient closed-circuit grinding operations.
03

Magnetic Separation and Purification

Tailored to the specific impurities and ore characteristics, a combined process of low-intensity and high-intensity magnetic separation is employed. Utilizing specialized equipment such as wet drum magnetic separators and vertical ring high-gradient magnetic separators, this process effectively removes gangue and associated impurities, significantly boosting both the grade and recovery rate of the iron concentrate.
04

Concentrate Drying

The high-grade iron concentrate obtained from magnetic separation is dehydrated and dried using specialized drying equipment to remove excess moisture. This yields a final iron concentrate product with high purity, stable quality, and compliance with industrial smelting standards.
05

Wastewater Recycling System

All production wastewater is uniformly collected and purified in a thickener. The clarified water overflows and is recycled back into the production system, achieving a closed-loop water cycle. The settled sludge undergoes filtration and dewatering, with the dry solids being stockpiled for disposal. The entire process operates in a closed-loop, eco-friendly manner with zero external wastewater discharge.
