flotation method

Denver cells and Jameson cells are two flotation methods used.

Conventional flotation methods are adopted to extract lead and zinc concentrates.

Fine coal is cleaned using froth flotation methods.

Hippeastrum seed can be difficult to germinate directly in soil, however they can be successfully germinated via the flotation method.

Once the ore has been mined, it has to be separated from quartz, sometimes by froth flotation methods, resulting in relatively pure barite.

If the quartz penetrates too deep into the ore, or the iron, zinc, or lead content is abnormally high, then froth flotation methods are applied.

The most common zinc concentrate processed is zinc sulfide, which is obtained by concentrating sphalerite using the froth flotation method.

It was used in the 20th century for measuring density of minerals by the flotation method, but the use is discontinued due to the high toxicity and corrosiveness of the solution.

The egg production of the worms is so high that there is no need to use flotation methods, and they are readily found in simple faecal smears to which a drop of water has been added.

According to officials of the Black Clawson Company, one of the largest manufacturers of paper-recycling equipment in this country, the flotation method works best with larger ink particles in the 50 to 150 micron range.

The solution was invented in 1907 by the Italian chemist Enrico Clerici (1862-1938) and introduced to mineralogy and gemology in 1930s as a valuable liquid, which allowed separating minerals by density with a traditional flotation method.

This defence was successfully used in Minerals Separation North American Corp. v. Noranda Mines Ltd., where a mining company sued another for the use of a patented process using a xanthate frothing flotation method in order to separate minerals from ore.
