The objective of this study was to investigate the effect of polymer (GLP-100) and surfactant (MFOMAX) towards the efficiency of oil removal in a flotation column by using the Response Surface Methodology (RSM). Various concentrations of surfactant (250, 372 and 500 ppm) and polymer (450, 670, and 900 ppm) produced water were prepared. Dulang crude oil was used in the experiments. Flotation operating parameters such as gas flow rate (1–3 L/min) and duration of flotation (2–10 min) were also investigated. The efficiency of oil removal was calculated based on the difference between the initial concentration of oil and the final concentration of oil after the flotation process. From the ANOVA analysis, it was found that the gas flow rate, surfactant concentration, and polymer concentration contributed significantly to the efficiency of oil removal. Extra experiments were conducted to verify the developed equation at a randomly selected point using 450 ppm of polymer concentration, 250 ppm of surfactant concentration, 3 L/min gas flowrate and duration of 10 min. From these extra experiments, a low standard deviation of 1.96 was discovered. From this value, it indicates that the equation can be used to predict the efficiency of oil removal in the presence of surfactant and polymer (SP) by using a laboratory flotation column.

Leaching Residue

Gold ore is processed by all-sliming cyanidation CIP (carbon in pulp) at a gold mine in Gansu province of China. The leaching residue (tailing) Au grade is about 0.52 g/t, which is much valuable to be recovered. Mineralogical analysis shows that the loss of gold in leaching residue is mainly organic carbon adsorption gold and inclusion gold, accounting for 45.55% and 54.45% respectively. The inclusion gold is mostly wrapped by gangue and metallic mineral separately, accounting for 35.56% and 18.89%. Excluding the gold in gangue, both the gold adsorbed by organic carbon and wrapped in metallic mineral could be recycled by flotation process. Study has been carried out for recovering gold in cyanide residue by solely column flotation apparatus. During the semi-industrial test, B and E type sparger were adopted in flotation columns to evaluate their influence on process performance. To further improve metallurgy technology the ultrasonic device was introduced into flotation column tank. The results showed that ultrasonic pretreatment is negative influence, and the E type sparger is better than B type sparger. The concentrate Au grade is up to 10.14g/t, and34.3% of Au lost in tailing was recovered while feed grade being 0.52g/t. The column flotation process was proven being a proper way to recycle gold from the tailing of all-sliming cyanidation CIP.
