Beneficiation operations form the core process of iron ore processing. Process monitoring and control constitute a vital component of beneficiation automation, requiring management of numerous parameters with diverse and complex characteristics. In this process, iron ore undergoes classification via classifiers and collection via collectors to produce iron concentrate.
This study examines three mainstream approaches: upward-level point-pillar non-cemented filling, upward-level layered and drift cemented combined filling mining, and pre-controlled roof segmental post-mining filling. A comprehensive comparison is conducted across structural parameters, development and caving methods, mining processes, and technical-economic indicators.
Process control for crushing operations primarily employs interlocking control systems. Utilizing advanced, reliable sensors and detection instruments enables the system to automatically monitor critical parameters such as oil pressure and temperature. This allows for the assessment and determination of whether crushing equipment like jaw crushers and cone crushers is operating normally.
After open-pit gold mining, the resource recovery of low-grade ore or waste rock is crucial to improving the overall economic efficiency of the mine. Heap leaching technology, with its low production cost, high economic efficiency, relatively simple process, and rapid results, has become an ideal choice for processing such materials.
As a vital manganese resource, manganese carbonate ore typically exhibits low grades, fine grain sizes, and complex mineral compositions. Direct smelting or processing not only yields low efficiency but also generates substantial waste residues.
The implementation phase of gold mining constitutes the core of the entire process, with the primary task being the extraction of gold ore from the surface or underground. The burial depth and geological conditions of the gold deposit determine the selection of mining methods. Based on the specific characteristics of the mining area, mining methods are categorized into open-pit mining and underground mining.
The comprehensive adoption of automation technology integrates isolated unit operations—crushing, grinding, and separation—into a cohesive, efficient, stable, and low-consumption system through intelligent sensing, precise regulation, and collaborative optimization.
In mineral processing, grinding is a crucial step between crushing and separation. Its core task is to grind the ore to a size that allows the mineral particles to be effectively separated into individual particles. Given different ore properties and production requirements, choosing between single-stage and two-stage grinding is a primary issue that every mineral processing plant design must address.
On January 16th, the "Mongolian Capital Market Connectivity: Investment and Mining" event, jointly hosted by the Mining Professional Committee of the China-Asia Economic Development Association and the Mongolian Financial Regulatory Committee, was held in Beijing.
To unlock the potential value of iron tailings, we must first choose a scientifically sound treatment path based on their characteristics. Currently, mainstream and efficient technologies focus on three main areas: dry tailings disposal, wet tailings disposal, and iron tailings reprocessing.
