MTW European type grinding mill helps gold ore grinding project successfully put into operation
As a precious natural resource, gold ore is the main source of gold. Gold mine powdering is crucial in the development and utilization of gold mines. Fine crushing of gold ore can significantly increase the recovery rate of gold. In the fine powder state, the contact area between gold ore and chemicals is greatly increased, which can fully expose the gold in refractory gold ores and lay a solid foundation for efficient gold extraction. At the same time, it plays a key role in process optimization and can accurately select appropriate mineral processing processes based on different ore properties, greatly improving production efficiency. In addition, it is also conducive to the comprehensive recovery of associated minerals.
Project overview
This project is a newly built gold mine resource utilization project by a well-known domestic mining company. The company actively practices the concept of clean production and introduces new gold mining and processing technology. It uses MTW European type grinding mill to grind the gold ore into powder and then carries out the subsequent gold extraction process. It significantly improves production indicators and achieves energy saving, consumption reduction and cost reduction. pollution and efficiency goals. After the project is completed, it will fully demonstrate its significant advantages in the field of gold resource utilization.
The gold mine pulverizing production line consists of Liming Heavy Industry MTW European type grinding mill and related supporting equipment. It fully combines the user's site conditions, with reasonable process design and compact layout. During the equipment installation process, Liming Heavy Industry's technical engineers reasonably coordinated and arranged all links with high standards, high technology, high quality, and high efficiency, and provided professional training to on-site operators to ensure that the personnel could master the operation methods of the equipment.
Processing materials: gold ore

Production process
1. Cyanide gold extraction process
2. The powdering process of European type grinding mill
The ore raw materials are uniformly, quantitatively and continuously fed into the main milling chamber through the frequency conversion belt feeder for grinding. The ground materials are sent to the powder separator by the air flow of the fan for classification. Under the action of the analyzer, the materials that do not meet the fineness requirements fall into the grinding chamber for re-grinding, while the qualified materials enter the cyclone powder collector through the pipe with the air flow. Within, it is separated and collected, and the finished powder is discharged through the discharging device. The separated airflow enters the fan through the return air duct at the upper end of the cyclone powder collector. The production system operates under negative pressure and sealed conditions and is equipped with a pulse dust collector to prevent dust spillage and comply with national environmental protection standards.
