    Abstract: The invention relates to the technology of recovery of rare-earth elements form both solid fossil and technology-related materials obtained by means of their target-oriented processing. Rare-earth elements recovery method include the acid teaching of ground to less than 100 μm solid fossil and technology-related materials with the mixture of sulphuric and nitric acid at ratio from 6:1 to 1:1 mass parts, at the concentration in mixture of acids less than 15 wt. % at liquid/solid phases ratio of L:S from 2:1 to 6:1 mass parts. During the teaching operation progress the vacuum-impulse action is conducted curing all operation of transferring of rare-earth elements compounds into a solution and obtaining of a precipitate of remained solid fossil and technology-related materials. The obtained precipitate of solid fossil and technology-related materials is separated from leaching solution.Separation of rare-earth elements from teaching solution is conducted using Ion-exchange filter or membrane filter.

    Abstract: Invention refers to the pneumatic transport field, namely to vacuum-pneumatic transportation of bulk materials of high mass concentrations.Summary of the invention consist in that the material delivering from zone under atmospheric pressure into zone under vacuum is performed, at that vacuum is created by alternate action of vacuum impulses from one of two or more vacuum receivers connected to continuous vacuum source in such a way that under vacuum impulse action from one of receivers it synchronically, for the vacuum, action duration period, disconnects from continuous vacuum, source and the following receiver connects to continuous vacuum source.Invention allows transporting the bulk material of high concentrations through pipelines of long distances and having the sections of changeable transportation directions (vertical slope.)
