Rectifiers: Everything You Need to Know | Custom
Essentially, a rectifier is an electrical device used to convert alternating current (AC) into direct current (DC) by allowing a current to flow through the device in one direction only. Diodes work like one-way valves within the rectifier to maintain this flow of current. Rectification is the general way to describe this process.

SX EW Capital & Operating Cost of Solvent Extraction
As a result each mixer settler is ½ the size of those in the 2×1 circuit and the total settler area is only 66.7% of that of the 2×1 circuit. The cost saving is estimated to be about 29% which gives a capital cost of $5.0 million. The electrowinning capital cost is the same for each plant and is based on a copper production of 27.2 tonnes/day.

Electrowinning of iron from sulphate solutions
In recent years very little has been published in the literature about electrowinning of iron from mineral ores in acid electrolytes. However, a related problem has been addressed in connection with the recovery of Zn and Fe from spent pickling solutions (Csicsovszki et al., 2005).Here iron deposition from hydrochloric solutions was studied in a two-compartment cell using an ion-exchange membrane.
