The bionest system results in a longer SRT, good sludge mixing, and reduced wash-out of sludge.
Wood impregnated by this method has good antiseptic properties against wood-decaying and wood-colouring fungi as well as reduced wash-out of the active agents.
Anu Adhikari, IUCN, discussed risks related to poor road construction in Nepal, including soil erosion and wash-outs.
leaching of underground waste depositories
A leach bed is formed of the agglomerated ore and the bed is leached with a leaching agent to thereby form a leach liquor.
Controlled-leaching preparations containing a physiologically active substance unstable in acids, in particular, pulsed-leaching preparations being slight in lag time fluctuation and enhanced in reliability of leaching performance.
A process for leaching platinum and palladium wherein an aqueous leaching solution containing bromine and bromide ion contacts a precious metal source to produce an aqueous leachate.
The process may be used in a pulping stage, a bleaching stage or can be used for both the pulping and bleaching stages of a delignification process.
It is itself founded on the distinction of the main pedogenetic processes leading to soil differentiation: brunification, lessivage, podzolisation, hydromorphy, etc.
A device for preventing soil wash out during subsea drilling is shown and described, having means for retaining the soil around a sub sea anchor foundation (7).
The cemented carbide insert bars (50a, b, c, d) form an upper composite matrix that helps to reduce wear and the premature wash out of the hard material insert bars (50a, b, c, d) integrally cast within the central feed body (20).
This process of ultrasonically assisted solid-liquid extraction is known as sono-leaching, lixiviation or washing.
The invention relates to a composition for cyanide lixiviation, comprising at least one non-ionic surfactant, and to a method for the production of metals using the above-mentioned composition.
The cellulosic fiber material is impregnated with polysulfide before cooking followed by extraction of spent cooking liquor.
The metal values are recovered from the leach liquor.
In order to produce cellulose by boiling starting materials with boiling liquid in a cellulose digester that functions either continuously or discontinuously, the progression of the boiling should be directed.
The trough (8) is known as a washout trough.
The invention also relates to the digester additive compositions.
The reconstituted acid is then recycled to the leach step.
The hydrogen sulfide is stripped from the leach solution, thereby reducing the amount of sulfate generated in the leach to very low levels.
Quantitative results of the leaching process are given.
Since 2002-2003 leaching rates are almost constant.
leaching in rain and foliar absorption ( foliar uptake ) at the shrub layer or stratum
A slag is thereby obtained with excellent leaching resistance.
The leach solution reacts with mineral elements and compounds in the soil samples to produce a leach reaction solution.
The invention also relates to the use of sulphur-containing amino acids or their derivatives in the leaching of sulfide-containing materials with microorganisms, especially the leaching of pyrite.
Closed brown stock screening and efficient brown stock washing
Leaching is performed in the presence of both divalent and trivalent iron and preferably with the dissolved copper acting as a catalyst to promote leaching.
