Improve your mining separation processes
Maximize the results of processes like flotation and thickening thanks to precise instrumentation
Declining ore grades pose a special challenge for mining operations. Of course there are various processing techniques to get the most out of the raw materials like leaching, thickening and flotation. But naturally they consume energy, chemicals and water. Which means that, to balance out the yield and the costs, the extraction processes must run at an optimum level. Especially in times of volatile markets and prices.
Our products, services and solutions for you
Leaching, flotation and thickening are fundamental steps in modern mining separation processes. Achieving an optimal separation however is a complex task due to the many interconnected variables. All three processes use chemicals which are one of the main cost drivers. And they consume also a lot of water, which in some mining regions can be a very scarce resource, which the plants first have to produce through processes like desalination of salt water for example.

Application
Leaching
Leaching is an extraction method that uses acid solutions that are sprayed on crushed ore to generate a pregnant solution with the desired metal. The acids used depend on the type of ore to be leached.
Our expertise in the field
It has been shown that the concentration and the irrigation flow rate of the acid solution has a significant impact on the yield and the acid consumption. Sentasy can offer measuring instruments for parameters that can withstand the aggressive nature of the acids and deliver reliable data.
Froth flotation
Flotation is used in various mining processes, such as gold and copper mining, to recover mineral particles which are finer than 500 micron or 35 mesh. Various parameters influence this process and by that your yield. The most important parameters for process efficiency are: flow and density measurement of feedstock, froth height, precise determination of the froth and liquid slurry interface, liquid pH and Eh, dosing and quality of chemical reagents and air flow.
Our expertise in the field
Sentasy not only has instruments for all these tasks but also offers a variety of measuring technologies to ensure you can use the optimum instrument for your process – all from a single source.
Thickener
Thickening is a mineral concentration process based on gravity settling. Solids settle on the tank bottom, a process which is accelerated by the addition of flocculent.
Our expertise in the field
Important indicators are bed level, bed mass, underflow density and flow to calculate the total slurry volume, and overflow clarity for final quality assurance. By measuring all these parameters, operators can make the whole process more efficient and safer by reducing the risk of tank overflow.
