Real-time Continuous Analysis in Non-Ferrous Metals Production
Real-time Continuous Analysis in Non-Ferrous Metals Production
Non-ferrous metals include light metals (lithium, aluminum, magnesium, titanium), heavy metals (copper, lead, zinc, nickel, tungsten, molybdenum, tin) and precious metals (gold, silver, platinum).
All ores that contain non-ferrous metals can be analyzed by the Lyncis online mineral analyzer, based on safe laser technology LIBS.
Lyncis cross-belt elemental analyzer can be used for continuous quality monitoring of non-ferrous metal material streams at different stages of the process (mining, stockpiling, preparation of mixes with the necessary ratios of controlled elements, leaching, final product quality control) directly on conveyor belts.
Lyncis SlurruView can also analyze slurry and liquids containing non-ferrous metals or elements from one or more streams if they are joined with 3rd-party multiplexors.
Based on reliable, accurate data from the Lyncis online analyzer, operators can respond immediately to changes in material characteristics without sampling and waiting for time-consuming, costly laboratory analysis.
Real-time continuous analysis in Alumina production
Many alumina refineries experience efficiency losses due to the variations in mineralogy and the presence of impurities such as silica, iron oxides and titania in bauxite (the main raw material used in the alumina industry), not only influence its processing efficiency, but can also increase production costs and create quality deficits in the final product. With real-time data received from Lyncis OnLine analyzers, it is possible to manage variations in bauxite, reject unacceptable material, blend different grades of bauxites, make real-time adjustments to the addition of lime, sodium hydroxide and other process raw materials and reagents, and to provide improved measure of product quality control. Growth in the global alumina supply and the tendency to process lower grades of bauxite in future will only intensify the demand for reliable tools for real-time measurements. These measurements can provide the data required to manage impurities, and to make prompt corrections to process parameters without the potential delays of up to several hours for sampling and laboratory based results.
Bayer alumina production process efficiency improvement with online analysis
- Control variations in quality of crushed bauxites to reject off-grade material and optimize blending before being mixed with a caustic soda solution
- Accurate dosage of lime, caustic soda (NaOH) to optimize digestion and reduce operating costs
- Control of Alumina/Caustic ratio in the hot slurry to the specified target
- Red mud chemistry control
- Quality control of alumina to avoid negative influence on aluminum metal products
Non-ferrous metals production technology improvement by online control
- Real-time control the quality to prevent discarding of commercially valuable ore to the waste

- Chemical homogeneity of the ore
- Reduced consumption of water, energy and flotation reagents
- Improved beneficiation/leaching process
- Stable technological process
- Improved final product quality
- Eliminated human errors and reduced costs for laboratory analysis.
