Obtaining pure uranium and compounds for industrial and military applications.
Extraction of uranium:- extraction from underground mines- open pit mines- leaching
Actinium is separated from uranium ores residues, after the extraction of uranium, radium and polonium; classical methods for separation in chemistry are used but the process is long and difficult.

1. Actinium is separated from uranium ores residues, after the extraction of uranium radium and polonium; are used classical methods in chemistry but the process is long and difficult. 2. Actinium isotopes can be also artificially prepared by the intermediate of nuclear reactions as:
Extraction is the process of separating a desired substance from a mixture using a solvent. This method is often used in chemistry and industry to isolate specific components for further processing or analysis. Extraction can be performed using various techniques such as liquid-liquid extraction, solid-phase extraction, or steam distillation.
Uranium
The symbol U in chemistry stands for uranium. Uranium has 92 protons, making it the element with 92 on the periodic table.
In chemistry, "UG" stands for "Uranium Glass."
Two common separation techniques used to extract uranium are solvent extraction and ion exchange. Solvent extraction involves using an organic solvent to selectively extract uranium from a liquid mixture, while ion exchange involves using a resin to selectively adsorb uranium ions.
A good chemistry teacher know all about uranium !
In the past uranium mining was a source of environment contamination.Now the negative effects are minor and is possible to be remedied.
The problems are:- radioactivity and toxicity of uranium- release of radon- generally low concentration of uranium in rocks- possible contamination of the environment
