摘要： A process for removing, by absorption, sulfur dioxide from a gaseous mixture such as a flue gas by scrubbing said mixture with an aqueous scrubbing liquor to which a solution of an alkaline reagent such as sodium carbonate is added to maintain alkalinity of the scrubbing liquor. The solution also has dissolved in it a quantity of silica which tends to precipitate when solution is added to the scrubbing liquor. The silica precipitated in this manner tends to form extremely hard solid deposits in the scrubbing device and associated equipment. If a water soluble acid salt such as ferrous or ferric sulfate is added to the alkaline reagent solution prior to its use in the process, the precipitate formed has a minimum deleterious effect.

摘要： The present process involves an improvement in the hydrometallurgical recovery of metal values from metal bearing sources such as ores and the like. When subjecting a metal bearing source to a reductive roast in a reducing atmosphere followed by cooling the reduced metal bearing source, extracting the cooled source and recovering the resultant nickel value, it is possible to utilize a smaller amount of an additive which assists in the recovery of metal values by scrubbing the off-gases from the reductive roast utilizing a fresh metal bearing source feed as the scrubbing material.

摘要： Metallic lead may be obtained from lead bearing sources such as lead sulfide ores or concentrates by halogenating the lead source, brine leaching the lead halide to separate the soluble lead halide from solid material such as gangue and recrystallizing the lead halide at a reduced temperature. Following this the lead halide is then converted to lead carbonate by treating the lead chloride with sodium bicarbonate. Thereafter the lead compounds are solubilized in hydrofluosilicic acid and subjected to electrowinning to produce lead sheet on the cathode.

摘要： Titanium metal values may be recovered from iron and titanium bearing sources such as an ilmenite ore by subjecting the source to a reductive roast after having crushed the source to a desired particle size. The reduced source is then leached by treatment with a halogen-containing compound to form soluble titanium halides and iron halides. Thereafter, the soluble titanium halide is precipitated as titanium dioxide by treatment with an iron oxide such as ferric oxide. The desired titanium dioxide or rutile may be recovered without an appreciable loss by effecting the leach step of the process in such a manner so that the solution potential is not greater than about +150 millivolts.

摘要： A process for reducing the concentration of selenium ions in the Se(VI) oxidation state in an aqueous solution. The aqueous solution is admixed with a quantity of metallic iron. The iron reduces the selenium ions from the Se(VI) oxidation state to a lower oxidation state and then dissolves in the aqueous solution. If the pH level of the aqueous solution is above about 2.3, the selenium ions are reduced to at least the Se(IV) oxidation state and the dissolved metallic iron hydrolyses to form an iron hydroxide that precipitates. The precipitated material is separated from the aqueous solution to provide a solution having a lower concentration of selenium ions. If the pH level of the aqueous solution is below about 2.3, no iron hydrolysis is observed to occur. At least a portion of the selenium in the Se(VI) oxidation state is believed to be reduced to the elemental state. The elemental selenium then is separated from the aqueous solution to provide a solution having a lower concentration of selenium ions.
摘要翻译：一种在水溶液中降低Se（VI）氧化态硒离子浓度的方法。将水溶液与一定量的金属铁混合。铁将硒离子从Se（VI）氧化态还原成较低的氧化态，然后溶解在水溶液中。如果水溶液的pH值高于约2.3，则硒离子被还原成至少Se（IV）氧化态，溶解的金属铁水解形成沉淀的氢氧化铁。将沉淀的材料与水溶液分离以提供硒离子浓度较低的溶液。如果水溶液的pH值低于约2.3，则不会发生铁水解。硒（VI）氧化态的硒的至少一部分被认为降低到元素状态。然后将元素硒与水溶液分离，以提供硒离子浓度较低的溶液。
