Effects of flotation solutions on sodium o-phenyl phenate,

Aug 01, 2005· ‘Comice’ pears (Pyrus communis) were immersed in dump tank solutions for pear flotation containing calcium lignosulfonate, sodium carbonate, potassium carbonate, potassium phosphate + potassium pyrophosphate, calcium chloride or sodium sulfate as flotation agents, alone or with 0.15 or 0.30% sodium o-phenyl phenate (SOPP). Phytotoxicity associated with SOPP was dependent onSodium Silicate - Agricultural Marketing Service,47 tree fruit and fiber. The primary organic handling use of sodium silicate is for floatation of fruit, especially 48 pears. Sodium silicate is added to fruit processing water to increase the density of the water, which allows 49 the pears to float (Willett et al., 1989). Pear floatation is used to prevent damage to the fruit duringEffects of flotation solutions on sodium o-phenyl phenate,,‘Comice’ pears (Pyrus communis) were immersed in dump tank solutions for pear flotation containing calcium lignosulfonate, sodium carbonate, potassium carbonate, potassium phosphate+potassium,

1 Froth Flotation – Fundamental Principles

1 Froth Flotation – Fundamental Principles Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry. The particles with attached airFlotation Reagents - Mineral Processing & Metallurgy,Some factors adversely affect the efficiency of anionic flotation of phosphate in the absence of sodium silicate, thereby decreasing the concentrate grade. Impurities originally present on the quartz surface might be responsible for this adverse effect, but the precipitates heterocoagulated onto the surface of quartz also appeared to play a role. Dissolved ions, especially Ca++, can be present,Effects of flotation solutions on sodium o-phenyl phenate,,‘Comice’ pears (Pyrus communis) were immersed in dump tank solutions for pear flotation containing calcium lignosulfonate, sodium carbonate, potassium carbonate, potassium phosphate+potassium,

pears float. Generally, sodium carbonate (soda ash), sodium sulfate, and sodium silicate are added to dump tank water until the pears float. In the dump tank, dirt and debris from the orchard accumulate. So do spores of numerous fungus species which may cause apples and pears to decay.
