Downstream processing Wikipedia

Downstream processing refers to the recovery and the purification of biosynthetic products, particularly pharmaceuticals, from natural sources such as animal or plant tissue or fermentation broth, including the recycling of salvageable components and the proper treatment and disposal of waste. It is an essential step in the manufacture of pharmaceuticals such as antibiotics,

Filtration Wikipedia

Filtration is a physical, biological or chemical operation that separates solid matter and fluid from a mixture with a filter medium that has a complex structure through which only the fluid can pass. Solid particles that cannot pass through the filter medium are described as oversize and the fluid that passes through is called the filtrate. Oversize particles may form a filter cake on top of

Bioleaching of a low grade sphalerite concentrate produced

Flotation process was applied to produce a sphalerite concentrate from tailings. The tailings were conditioned in a pulp with a pH of 5.3, 600g/t CuSO 4, 400g/t FeSO 4 and 10g/l frother (MIBC). About 45% of sphalerite was floated in the flotation stage. Chemical analysis and mineralogical compositions of the concentrate is presented in Table 1.

Comparison of the effiency of aluminium and ferric

In the middle of the study, the coagulation/flotation process was modified by replacing the aluminium sulphate by ferric sulphate. At the same time, the filtration unit was enhanced by adding a sand filter unit before the activated carbon filtration and by changing new carbons on to the activated carbon filters. A special aim was to compare the efficiency of the aluminium and
