pregnant leach solution (PLS) derived from the leaching of e-waste was investigated. The effects of impurity ions (Co 2+, Fe 3+ and Cl - ) and additives (thiourea and gelatine) on the corrosion ...
The resulting "pregnant" leach solution of sulfuric acid and copper sulfate is collected in a small pool. The copper compound can now be seen at concentrations of between 60-70%. The second step is solvent extraction, in which two immiscible (un-mixing) liquids are stirred and allowed to separate, causing the cooper to move from one liquid to the other.

Solution Process Ponds § The solution collection ponds will collect and store 100 percent of the operational solutions. § Ponds will contain any temporary drain down and 100-yr 24-hr design storm flows within the lined leach pad area. § Ponds include a double-lined Pregnant Leach Solution pond, double-lined Raffinate pond and a single-lined Stormwater pond.
08-09-2020· Hazard Communication Standard: Safety Data Sheets. The Hazard Communication Standard (HCS) (29 CFR 1910.1200(g)), revised in 2012, requires that the chemical manufacturer, distributor, or importer provide Safety Data Sheets (SDSs) (formerly MSDSs or Material Safety Data Sheets) for each hazardous chemical to downstream users to communicate information on these .
The process plant, located near to and down-gradient from the heap leach facility HLF to minimize the pumping and pipeline requirements for pregnant and barren solutions, will operate 365 days per year. The pregnant solution will flow to the plant at a nominal rate of 455 m3 /h and a .
Pregnant leach solution flowing from the bottom of the heap was collected in a pond created by placing a dam downstream from the leach area. The ... copper starter sheets at a current density of about 180 A/m2 with a current efficiency of 80 to 85%. The anode was 6% Sb in Pb.
Thus, the leach solution is pumped into a vacuum deaerator for removal of oxygen and other gases which typically reduces the oxygen content of the cyanide solution to about 1 ppm or less through the use of a deaeration tower filled with packed media.

26-09-2019· The so-called 'pregnant' leach solution (or pregnant liquor) is then processed using a hydrometallurgical process known as solvent extraction and electro-winning (or SX-EW). Solvent extraction involves stripping the copper from the pregnant liquor using an organic solvent, or extractant.

Current mining practices using lower concentration leaching solutions generate large volumes of pregnant leach solutions (PLS), which favors the use of ion exchange (IX) for the recovery-purification step because IX can more economically concentrate uranium from large volumes of PLS. Many different engineered IX systems are used in uranium mining.
