GEOSCAN – M is used for minerals applications including ore and concentrate analysis. Units are currently installed in iron ore, phosphate, manganese and copper mining and processing operations to provide real time, full stream analysis for process control. The multi-element analyses are transmitted to the control system as weighted averaged dry weight percent through the use of belt weigher and moisture analyser inputs. Whether at the mine site, at the treatment plant or at the smelter, Scantech offers solutions that aid the blending, handling and monitoring of various minerals, ores and products.
Process control technology has undergone an amazing revolution in recent years, chiefly because of Prompt Gamma Neutron Activation Analysis (PGNAA) technology. Enabled by enhanced electronic digitisation, PGNAA has led to a new era in process control. The key to our success is also providing an easy to use, yet sophisticated user interface, that can be easily and quickly integrated into each plant to ensure maximum return on investment.
"When commodity prices were strong and rising, mining companies could afford minor inefficiencies in their plants. That is rarely the case in these days of lower-grade deposits, lower metal prices and economic pressure from every direction. “We have to do better with lower costs,” said Philip Thwaites, manager of process control for XPS Consulting & Testwork Services. “If you’re not efficient, you’re not going to be around. And our industry can be a lot more efficient.” According to Thwaites, measurement is the cornerstone of control and efficiency. “If you have a poor measurement, or no measurement, you can’t do good control,” he explained. But this is changing. More and more mining companies are conscious of improved measurements and endorsing control, automation and next-generation technologies. What is more, there has been significant progress in automated instruments recently. These measure crucial parameters in the processing circuit and equipment to allow operators to monitor and adjust process control as needed."
