article{osti_5182950, title = {Extraction of trivalent actinides and lanthanides from nitric acid solutions by ion flotation}, author = {Mezhov, E H and Samatov, A V and Troyanovskiy, L V}, abstractNote = {To determine whether the deep extraction of trivalent actinides from liquid active waste is feasible, the authors made a detailed investigation into the ion flotation of europium (as a The fluoborate ion was found to bind with an alkylamine acetate by displacement of the acetate group and can be removed from dilute waste stream either by air flotation or ultrafiltration. A high density low porosity graphite anode that is resistant to the corrosive properties of fluoboric acid electrolyte was developed for electrodialysis treatment of the tin, solder and copper fluoborate

2019/8/26Apparatus for separating solids from solids are covered by B03B when the process concerned is regarded as the equivalent of washing in the sense of the mining art, even if such apparatus is a pneumatic one, especially pneumatic tables or jigs. Screens PER SE are not covered by this subclass but are classified in B07B, even if they are being used in a wet process.

The solid phase materials or sorbents applied to the removal of uranium from industrial waste streams and surface waters are reviewed. The speciation of the element in the environment is discussed. A series of examples on uranium remediation from the recent literature using the different kinds of solid phase sorbents are reviewed in detail and evaluated. The criteria for making the best choice

Ion-exchange Sludge dewatering TECHNOLOGY Industrial wastewater can contain a variety of contaminants. A ready-made solution is therefore only the second best choice. We develop individual systems for all types and levels of load so your wastewater is

It is already known that the flotation of iron bearing oxide minerals with fatty acids can be improved by activating them with an ion of a heavy metal (e.g. U.S. Pat. No. 2,861,687). Because the activation-conditioning step has been carried out by the conventional way in cold pulp, the results are, with reference to the explanatory part of the said patent, in many ways unsatisfactory:

Desalination is a process that takes away mineral components from saline water.More generally, desalination refers to the removal of salts and minerals from a target substance, as in soil desalination, which is an issue for agriculture. Saltwater is desalinated to produce water suitable for human consumption or irrigation..

Solid-phase extraction (SPE) is an extractive technique by which compounds that are dissolved or suspended in a liquid mixture are separated from other compounds in the mixture according to their physical and chemical properties. Analytical laboratories use solid phase extraction to concentrate and purify samples for analysis. Solid phase

Gold cyanidation (also known as the cyanide process or the MacArthur-Forrest process) is a hydrometallurgical technique for extracting gold from low-grade ore by converting the gold to a water-soluble coordination complex.It is the most commonly used leaching process for gold extraction.

The ultrapure water may be further treated by utilizing ion exchange media and degasification apparatus. A control system can be utilized to regulate addition of the precursor compound, the intensity of the actinic radiation, and addition of the reducing agent to the water.

Characteristics Physical properties Zinc is a bluish-white, lustrous, diamagnetic metal, though most common commercial grades of the metal have a dull finish. It is somewhat less dense than iron and has a hexagonal crystal structure, with a distorted form of hexagonal close packing, in which each atom has six nearest neighbors (at 265.9 pm) in its own plane and six others at a greater distance
