摘要： A process for recovering and purifying nickel (Ni), manganese (Mn), cobalt (Co), and lithium (Li) from black mass obtained from recycling of lithium-ion batteries to produce high purity products. The process may include reductive acid leaching, impurity removal, precipitation of valuable metals such as Ni, Co, Mn, and Li. The process may also include recycling of Li compounds as hydroxide or carbonate as a source of alkaline reagent for impurity removal and/or precipitation of the valuable metals.

摘要： In-situ solution mining method of an ore bed, particularly containing trona, which comprises exposing to a solvent an ore region inside a borehole drilled in the ore, and dissolving a desired solute within the exposed region to provide a liquor and create a voided ‘undercut’, such undercutting making the ore susceptible to gravitational loading and crushing. Unexposed ore falls into the undercut by gravity without breaking the ore roof resulting in exposure of fresh ore to the solvent and in preventing solvent exposure to contaminating material near the roof. The desired solute is eventually dissolved away in the entire bed from its floor up to its roof. Solvent injection may be delivered through a conduit positioned inside the borehole, and may be moved by retracting or perforating the conduit. The method may employ an advancing undercut initiated up-dip and traveling down-dip, or a retreating undercut initiated down-dip and traveling up-dip.
摘要翻译：特别是含有天然碱的矿床的原位溶解开采方法，其包括将矿石中钻出的钻孔内的矿石区域暴露于溶剂中，并将期望的溶质溶解在暴露的区域内以提供液体并产生空洞的“ 底切“，这种底切使得矿石容易受到重力负荷和粉碎。未暴露的矿石通过重力落入底切而不会破坏矿石顶部，导致新鲜矿石暴露于溶剂并且防止溶剂暴露于屋顶附近的污染物质。所需的溶质最终从其地面溶解在整个床中直至其屋顶。溶剂注入可以通过位于钻孔内的导管输送，并且可以通过缩回或穿孔导管来移动。该方法可以采用推进的底切开始的上行和下行行驶，或者采用后退下行开始的下行行驶和上行行驶。

摘要： Cesium is recovered from a cesium-bearing mineral such as pollucite by extraction with hydrochloric acid to obtain an extract of cesium chloride and other alkali metal and polyvalent metal chlorides. The iron and aluminum chlorides can be precipitated as the hydroxides and separated from the solution of the alkali metal chlorides to which is added potassium permanganate or other water-soluble permanganate to selectively precipitate cesium permanganate. The cesium precipitate is then separated from the residual solution containing the metal chlorides. The cesium permanganate, which is in a very pure form, can be converted to other cesium compounds by reaction with a reducing agent to obtain cesium carbonate and cesium delta manganese dioxide.

摘要： An alkali metal generating agent (1) for use in forming a photoelectric surface emitting a photoelectron corresponding to an incident light or a secondary electron emission surface emitting a secondary electron corresponding to an incident electron, which comprises an oxidizing agent comprising at least one vanadate having an alkali metal ion as a counter cation and a reducing agent for reducing the above cation. The above metal generating agent (1), which includes a vanadate having weaker oxidizing power than that of a chromate, undergoes slower oxidation-reduction reaction, which results in easier reaction rate control as compared to a conventional technique using a chromate, leading to the generation of an alkali metal with good stability.
