Although the effluent from these plants meets current state water quality regulations, more stringent demands are being instigated to remove a greater amount of the contaminants, such as phosphate, nitrate and total organic carbon, from wastewater before it is discharged into the receiving waters.
Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process. Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process.
Cyanidation carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution . In 1970s , with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold , make recycle the carbon and reduce the cost , and easy to process the gold

The PHOSPAQ process is applied to recover phosphate from effluents as struvite. Phosphate is becoming scarce, thus making recovery more and more interesting. PHOSPAQ is a cost effective technology compared to e.g. dosing of iron salts. Moreover, the produced struvite is an excellent slow release fertilizer for N, P and Mg.

Metallurgical ContentLearn CyanidationDevelopments in the Carbon In Pulp ProcessDesign Criteria Commercial Operations Cyanide is a lixiviant, or reagent that is used to leach, often in tanks, gold from a solid matrix and form a gold cyanide complex. The gold cyanide complex is then extracted from the pulp or slurry by adsorption onto activated carbon.

The gold cyanidation process is a primary method of gold beneficiation. Activated carbon is a critical component in the beneficiation of gold ore, allowing this widespread process to occur because of its ability to recover gold from the gold cyanide complex.
Laboratory findings include low normal serum calcium, moderately low serum phosphate, elevated serum alkaline phosphatase, and low serum 1,25 dihydroxy vitamin D levels, hyperphosphaturia, and no evidence of hyperparathyroidism. Hypophosphatemia decreases 2,3 diphosphoglycerate (2,3 DPG) causing a left shift in the oxyhemoglobin curve.

Fermentations at laboratory scale were carried out in triplicate ().As mentioned above, the hydrolysates used in fermentations shown in Fig. 1A, C and E were produced from different coffee pulp batches which resulted in different sugar concentrations. Irrespective of the coffee pulp material used, B. coagulans used the recovered sugars for growth and lactic acid production.
quot;A simple approach to optimizing the performance of an operating carbon in pulp (CIP) or carbon in leach (CIL) plant is presented. It is possible to reproduce the performance of an operating CIP or CIL plant in the laboratory, in small scale batch tests in which the rates of gold leaching and carbon adsorption are determined, coupled with mathematical models that translate the batch kinetic
