at a pilot scale is the Sequential Liquid-lignin Recovery and Purification (SLRP) system (Lake and Blackburn 2011, 2016; Kihlman 2016). Another key motivation for lignin recovery is to utilize it for such higher-value applications as carbon fiber, phenolic resins, and activated carbon (Coheen 1981; Pye
another material. Activated carbon is used to adsorb the gold out of solution. Because the cyanide ion forms very strong complexes with gold, it is the gold cyanide complex that is loaded onto the carbon rather than being deposited as metallic gold. Activated carbon, or charcoal as it is now less commonly known, is made from organic material such

Activated carbon is a processed form of carbon with small, microscale pores resulting in greater surface area exposed to the adsorbate molecules. Carbonaceous materials like wood, peat, coal, coke, petroleum, bones, coconut shells, etc., are the most common raw materials for activated carbon.
Changes in the thermal-oxidation behavior and other properties of gold-bearing waste activated carbon when milled in both a ball mill and a vibratory mill were investigated. It was found that significant changes occurred in the oxidation temperature of the vibration-milled waste carbon as a result of increases in surface area and mechano-chemical activation. The mechano-chemical action brought .
In the present work, a new low-cost activated carbon was prepared from paper mill sludge in order to remove Cr(VI) ions from aqueous solution. The effects of adsorbent dosage, pH, contact time, met.
