Technical Appliions Of Cresylic Acids To Flotation Use

The Toxicity Of Various Mining Flotation Reagents To

Jan 01, 1976 Of the four frothers tested, xylenol cresylic acid appears to be the most toxic to rainbow trout. Haw- ley 1972 reports this compound to be acutely toxic, causing 100, mortality of Daphnia in 72h at 0.1 mg l- 1, and 100o mortality of the goldfish, Caras- sius aurams in 6-Jan 01, 1976 Of the four frothers tested, xylenol cresylic acid appears to be the most toxic to rainbow trout. Haw- ley 1972 reports this compound to be acutely toxic, causing 100, mortality of Daphnia in 72h at 0.Cresylic acids can be stored, transferred, processed and disposed of safely when proper procedures and safeguards are employed in industrial use. Cresylic acid production is carried out in equipment designed to prevent exposure to workers and release to the environment.The mixture of cresols obtained from coal tar is called cresylic acid, an important technical product used as a disinfectant and in the manufacture of resins and tricresyl phosphate.

In the former, iron oxide is floated. Anionic reagents, such as petroleum sulfonates or fatty acids, are most commonly used. Structurally, these reagents have negatively charged ionic heads attached to long-chain organic tails.Mar 01, 1992 Further developments have resulted in their commercial use in the flotation treatment of barite, celestite, fluorite, apatite, chromite, industrial garnet, kyanite, mica and cassiterite.

Composition intended for the flotation of ores, comprising from 70 to 95 of a combination A of n-dodecyl mercaptan or NDM and of tert-dodecyl mercaptan or TDM, the NDMTDM ratio by weight of which is between 0.5 and 1.5, and from 5 to 30 of a product B composed of one or more aromatic or aliphatic compounds comprising from 4 to 100 carbon atoms, preferably from 5 to 40, and having ...Composition intended for the flotation of ores, comprising from 70 to 95 of a combination A of n-dodecyl mercaptan or NDM and of tert-dodecyl mercaptan or TDM, the NDMTDM ratio by weight of which is between 0.5 and 1.Froth flotation has over the years proven to be the most effective and efficient technique for REE beneficiation, using fatty acids sodium oleate, oleic acid, and linoleic acid and hydroxamates Io Crude Tar Acids, i.e., the phenolic substances found in the higher fractions of the tar distillates have been applied as froth-producing agents in the froth flotation process, which mechanically and economically separates associated solids such as coal and stone, ore and earth, etc.

Froth Flotation Flotation Reagents Dmr Sekhar Contents

Frothers Creating sufficiently stable froth is a prerequisite for flotation process. This is achieved by reagents called frothers. Methyl Iso butyl Carbinol MIBC is one popular frother. pine oil, eucalyptus oil, cresylic acid and long chain alcohols amyl alcohol are other known frothers.Frothers Creating sufficiently stable froth is a prerequisite for flotation process.

The role of flotation frothers is mainly to produce a large amount of foam in the pulp, so that the available minerals are effectively enriched at the interface between air and water to create the conditions required for flotation process.

Recommended reagents were ethyl- andor amyl xanthate as main collectors 0.110.22 kgt and Aerofloat 25 aryl dithiophosphates collector based on the reaction of cresylic acid with 25 P 2 S 5 as additional collectors with frothing properties, cresylic acid, andRecommended reagents were ethyl- andor amyl xanthate as main collectors 0.110.The Flottec 2000 series are water soluble salts exhibit a wide range of properties with respect to selectivity and froth character. The Dithiophosphates are effective in alkaline flotation circuits and are more selective than xanthates against pyrite at pH between 8 and 10. The Monothiophosphates are effective copper collectors in acid circuits and in LPF circuits.minimize risk with regard to distribution and use of cresylic acids. Progress is tracked in implementing the identified actions. Results of this review are communicated throughout the organization so that employees are aware of the specific ways in which we meet our commitment to product stewardship and how they can support the effort.
