Automated Process Control A Major Breakthrough Due to the fact that the original Knelson concentrator was developed for the alluvial gold mining industry, automated process control was not seen as a feature of critical importance. The original Knelson concentrator was called the MD, or Manual Discharge Series. The machine
Aug 01, 1995 The concentrator flowsheet. 3.1 Concentrator Automation and Instrumentation The Pyhasalmi concentrator was the first mining operation to install a digital process control system and to operate successful economic strategies as described by Eerola, Haapala and Nierni (Eerola, and Paakkinen, 1969 Haapala, 1967 Niemi, 966 Niemi and Paakainen, 1969).
The concentrator was designed to pro-duce 22 24 % Cu. concentrate from head value of around 1.5-1.3 % Cu. Due to change in the method of mining and the lowering of cut-off grade of mined ore, the grade has gone down drastically to 1.12 0 /0 which has posed process control problems to maintain and even to increase the concentrate grade without sacrificing
1) Knelson Concentrator is an excellent and efficient gravity separation equipment. Each configuration form has its advantages and disadvantages, and the appropriate process should be determined according to actual production and site conditions. 2) The choice of different form is determined by the ore properties of the selected minerals.

Advanced process control focus areas Advanced process control (APC) is a wide concept focused primarily on supervisory control. An APC approach may include any number of variables or types of algorithm or predictive models, and may even be very application-specific. On the concentrator studies, the APC controls the pump action for the UG2

The plant was originally designed to treat uranium ores with low lime-high vanadium content from the Lukachukai Mountains. The process utilized is known as the Acid Cure and had been developed for the most part by the AEC to increase recovery of vanadium values. Briefly, it involved pugging the ore with 10% water and 400-500 .
Jul 03, 2017 Changes in the concentrator operation and evolution of the mining at Bingham Canyon has led to much lower grade concentrate with high levels of either pyrite or gangue. The Smelter now treats concentrate ranging from a low of 16% copper to a high of over 30% copper with an average grade of 22% copper.

This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore).
molybdenum plant, main conveyors, pumping stations and utilities. The process is controlled from four control rooms for the concentrator, primary crusher, molybdenum plant, and filter plant. The main control room is at the concentrator the other three control only their respective processes. There are around 10,000 I/O points at the site.
Aug 25, 2021 When the ore gets to the concentrator, the grinded ore is again analyzed, and the recovery process is optimized with the help of IMA Slurry Sampling and Analysis Solutions. IMA Ore Trackers IMA also provides Sensor and RF ID tag-based ore analysis and tracking solutions.

In the processing stage, the mined material is transformed into usable raw material. For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking.
