Developing MudMax™ for Paste Thickener Bed-Level Measurement

Posted by Jerold Johnson on August 23, 2019

Numerous studies and papers have been devoted to the subject of thickener design and operation to achieve specified throughput and discharge densities. Mathematical models have been developed that present methods for sizing thickeners and predicting performance under varying process conditions. The compression effect of deeper beds on dewatering performance is a recognized phenomenon. This is one variable of many that are interrelated and influence thickener performance.

Maximize Precious Metals Recovery with CCD Circuits and High-Density Thickeners

Posted by Mick L. McCaslin, PE on March 28, 2017

Leaching (lixiviation) is commonly used for recovering a wide variety of metals from ores, including precious metals. A lixiviant dissolves the desired metals from the ore; cyanide leaching, for example, is widely used to extract gold.

Lixiviation is often followed by a Counter Current Decantation (CCD) circuit to recover the valuable mineral from the gangue.
