Understanding the Chemical Recovery Processes in Pulp & Paper Mills

The white liquor (NaOH and Na2S) from the clarifier is recycled to the digesters in the pulping area of the mill. At about 7 percent of kraft mills, neutral sulfite semi-chemical (NSSC) pulping is also practiced. The NSSC process involves pulping wood chips in a solution of sodium sulfite and sodium bicarbonate, followed by mechanical de-fibrating.

Higher performing liners + fast relining = higher throughput

The primary function of a grinding mill's liners is to protect the mill shell from the harsh milling environment, and to deliver energy to the charge to facilitate the grinding process. However, the Achilles heel in the mill operation, is that the aggressive mill operating environment wears the liners out, necessitating regular replacement at ...

Gold processing

Gold processing - Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then …

Copper Processing

When working with oxide ores, a hydrometallurgical leaching process is typically utilised. This process makes use of aqueous (water-based) solutions to extract and purify copper from copper oxide ores at normal temperatures. This process could include three steps: heap leaching, solvent extraction, and electrowinning. Heap Leaching
