Under our assumptions, a three-stage CCD circuit using paste thickeners outperforms a four-stage CCD with high-rate thickeners 97.6% vs 96.2% . The process choice is clear, unless high volumes of wash water are justifiable; which of course depends greatly on the values contained in the pregnant liquor.
Our small thickeners find their appli ions in a leaching circuit, flotation concentrates or any tailings. Thickeners are essential equipment in a Merrill Crowe CCD counter-current decantation circuit. Ideal for small mining operations, our slurry thickeners are manufactured in sizes of up to to 16" diameter using mild steel construction. Each has internal launder, feed-well and discharge ...

CCD thickeners: a retrofit opportunity uranium in electro winning, ion exchange or solvent extraction processes, the liquor solu - tion needs to be concentrated to extract the maximum possible amount of the dissolved metal from a mineral ...
CCD circuits PASTE and hIGh COMPACTION ThICKENER DELKOR takes its knowledge and experience of over 30 years providing thickeners for the mining industry and applies it to the extreme mechanical and process requirements needed when dealing with high yield stress underflows. The
thickening process is stabilized and a consistent underflow density is achieved. CCD circuits For a number of thickeners in series, such as a CCD circuit, the basic control philosophy for each unit remains as described. However, interconnection of control loops occurs down the circuit, leading to increasing disturbances in solids inventory.
A back-illuminated CCD must be relatively thin in order for photogenerated electrons to diffuse to the frontside pixel wells and be collected under the sites where they were created. Most CCDs are built on epitaxial silicon with layers that are 10–20 μm thick.
A charge coupled device is a highly sen-sitive photon detector. The CCD is divided up into a large number of light-sensitive small areas known as pixels which can be used to build up an image of the scene of interest. A photon of light which falls within How a Charge Coupled Device CCD Image Sensor Works
The common thickener underpins the performance of most hydrometallurgical facilities. Thickeners are simple, reliable, effective and efficient-under the right conditions.
