Abstract: FIELD: hydrometallurgy of nonferrous and rare metals. SUBSTANCE: invention aims at selectively separating and recovering purer product in solid phase of precipitate and aqueous phase of filtrate. In the first step, original solution is treated with inorganic precipitators to form precipitate consisting of carbonates, hydroxides, or hydroxocarbonates of those elements having lower precipitation pH value. Resulting filtrate containing elements with higher precipitation pH value is withdrawn as final product. Precipitate is used in the second step as precipitator to treat original solution. Second-step precipitate contains pure elements with lower precipitation pH value and is withdrawn from process, and filtrate is treated with inorganic precipitator as in the first step. In the first step pH value is maintained within 2-5 range, in the second step 0.5 to 3. EFFECT: improved element separation selectivity. 4 cl, 1 tbl

Abstract: FIELD: computer engineering. SUBSTANCE: method involves generation of two three-level signals   using Popov wave functions pop q (φ), which are represented by means of two orthogonal constituents pop q (φ) = cop q (φ)+isip q (φ).. Each integer k x  and k y  from k x,y  = 0 till k x,y  = q-1, in notation systems with base q = 4 and q = 8 are represented by phases φ x,y  = 2πk x,y /q. Each phase φ x,y  is encoded by values of signal levels cop q (2πk x,y /q) and sip q (2πk x,y /q). Values of orthogonal constituents of Popov functions cop q (φ) and sip q (φ) are detected by comparison to thresholds ±ξ of respective trigonometric functions cosφ and sinφ for argument values φ = 2πk/q. Phase addition is performed by generation of signals cop q (s) and sip q (s),; phase subtraction by cop q (-s), sip q (-s),, which represent codes of sum and difference of items k x  and k y .. Phase addition and subtraction follows standard equations for addition and subtraction of phases of sine waves.
