The Flotation Technique in Archaeology

May 03, 2012 The aim of flotation is to “recover animal bone, seeds, and other small cultural remains lost in the normal screening of soils from archaeological sites” (Struever 1968:353). As I understand this, faunal (animal) and floral (plant) materials is trapped in soil,

What is Archaeological Flotation? Zagora Archaeological

Sep 06, 2019 Flotation is one of the archaeobotanical sampling techniques used on site to investigate ancient plant remains. Flotation captures small finds including grains and seeds that would normally be missed during archaeological excavation.

Flotation. To recover very small artifacts and charred seeds and nuts, soil is "floated." In this process, the soil is dried, then poured into a bucket of water. Charcoal and other plant materials are lighter than the soil, and float to the surface. They are poured off into a screen with holes of 0.5 mm, which is finer than window screening.

Jan 11, 2016 The FLOTATION PROCESS is one of the commonest methods of extracting the valuable minerals from certain classes of ores, and it is generally more efficient as regards the recovery of the minerals than any other process applicable to the treatment of similar types of ores. The metallic contents of the minerals are recovered from the concentrates in a subsequent series of metallurgical

Molybdenite flotation from copper/molybdenum concentrates

Typically, rougher molybdenite flotation and recovery from bulk copper/molybdenum concentrates involves the use of alkalisulfides, Nokes reagents, cyanides, oxidants, and/or thermal treatment to depress copper sulfide minerals. The bulk copper/molybdenum feed generally varies from 0.2% Mo to 1.0% Mo, and with traditional reagents the single-stage rougher flotation recovery of molybdenite

Optimization of a Copper/Molybdenum Flotation Circuit by

Copper and molybdenum recoveries when occurring as sulfide minerals primarily rely on a process called flotation. This process was first patented by William Haynes in 1860 “who claimed that sulfides could be floated by oil and non-sulfide minerals could be removed by washing in a powdered ore” (6).

The main purpose of pretreating the copper-molybdenum mixed concentrate is to remove the residual collectors in the slurry in the most reasonable and effective way.

Apr 19, 2016 Copper and molybdenum flotation process is commonly used for copper and molybdenum ore with pretty high grade, while it’s rarely adopted in industrial production. In part combined flotation process, molybdenum with high floatability will be concentrated first, and then copper and molybdenum combined concentrate are concentrated together.
