Flotation (rotation) cost

The costs associated with creating capital through the issue of new stocks or bonds, including the compensation earned by the investment banker plus legal, accounting and printing expenses.

flotation

the process by which a new company or an established PRIVATE LIMITED COMPANY becomes a PUBLIC LIMITED COMPANY and issues SHARES to the general public. By going public a company is able to raise large amounts of capital by issuing a PROSPECTUS inviting shareholders to subscribe for shares. See SHARE ISSUE.

flotation

the issue of shares in a newly established or existing private company whereby the company goes ‘public’ and obtains a listing of its shares on the STOCK EXCHANGE. See SHARE ISSUE.

Experienced operators usually judge the flotation condition by the visual appearance of flotation froth, and earlier work has shown that the surface features of froth could reflect the production performance of froth flotation [2,11,12].
For the froth flotation tests, the following reagents were used: Calcium lignosulfonate (CaLS) from Aldrich; Hosta-phat (etanolic solution of alkane phosphonic acid) OPS75E, from Clariant Produkte; sodium hydroxide (NaOH) from Quimitecnica; Methyl Isobutyl Carbinol (MIBC) from CYTEC.
The first successful industrial-scale application of froth flotation was at Broken Hill, Australia, in 1905 for the recovery of fine-grained sphalerite from gravity separation tailings.
In the froth flotation process, ABS and HIPS, two plastics that are incompatible but have similar densities, are placed in an aqueous solution of a certain density, surface tension, and pH.
This slurry will usually pass through a froth flotation system where a chemical foaming agent is added.
The whole kernel corn is conveyed into a Key technology froth flotation cleaner, and then onto a Key Iso-Flo vibratory conveyor that feeds the corn evenly into the Turbo-Flo blancher.
The shaking table and dry magnetic separation technique was used for beneficiation of Fe-ores while froth flotation technique was applied for upgradation of Cu-ores.
The machine has had a successful impact in several sectors of the industrial minerals market for the collection of very coarse particles that were once believed to be unrecoverable by froth flotation technology.

Froth flotation is a surface chemistry-based process for separation of fine solids that takes advantage of the difference in wettability between the separated particles.
