| A process for the treatment of ground, spent potlinings generated during the production of metallic aluminum to reduce cyanide content to environmentally nonhazardous levels. Potlinings are ground or otherwise suitably reduced in size to a particle size of not greater than about 2 inches in any dimension and roasted in a stream of air or nitrogen at a temperature between about 500.degree. F. and 1400.degree. F. Roasting for an appropriate time-temperature interval reduces cyanide content to desired levels without combustion of a major portion of carbonaceous material, resulting in an end product rich in carbon and fluorine which may be salable because of this content. | ||||||

| A novel method for manufacturing cement utilizing crushed refuse. The method comprises a first step of preparing a homogeneous powder mixture from a majority of crushed refuse substantially free of metal constituents and a minority of at least one first mineral material containing calcium oxide in the free or combined state. In a second step, the powder mixture is granulated under pressure. A third step comprises heat treating the granules at a temperature between 130.degree. C. and 230.degree. C. for a length of time sufficient to bring the water content of the granules to between about 0.1 and 1.0% by weight. The third step produces a refuse product. A fourth step comprises mixing the refuse product with a first starting mixture and firing the resulting clinker mixture in a kiln, producing a clinker. In the last step, gypsum is added to the clinker and the resulting cement mixture is crushed. | ||||||
| 165 | Method and apparatus for treating water containing wastes | US35201 | 1979-04-30 | US4226712A | 1980-10-07 | Takeji Kamei |
| A method and apparatus for treating a water containing waste such as industrial sludges and animal excrements. The method comprises a first step of mixing the waste with an alkaline earth metal oxide such as calcium oxide to obtain a preliminarily dried mixture and a second step of further drying and granulation of the mixture. The apparatus comprises a reactor for a mixture of the waste and an alkaline earth metal oxide, a drying kiln equipped with a stirrer means, a furnace surrounding the drying kiln and an exhaust collector means adapted to collect an exhaust gas from the reactor and drying kiln and transfer it to the furnace. Fuel consumption is saved by utilization of the exothermic reaction of an alkaline earth metal oxide with water contained in the waste. The waste may be converted by the method to usable products such as fertilizers, cement materials or cement additives. The apparatus is so designed to overcome the problems of an offensive odor produced during processing and at the same time to minimize a loss of heat during the transportation of the mixture from the reactor to the drying kiln. | ||||||

| Solid, leach-resistant bodies are formed from aqueous heavy metal sludge and fly ash formed in the combustion of subbituminous coal from the Power River Basin by slurrying the sludge with an amount of fly ash equivalent to between about 20 wt. % and about 70 wt. % based on the weight of the slurry, wherein the initial liquid content of the slurry is such that the slurry will harden into a body having a 7-day compressive strength of at least about 250 psi, and allowing the slurry to harden. | ||||||

| The invention relates to a process for the production of alumina from mineral component of solid fuels containing aluminum, silicon and iron oxides. The process comprises burning a mixture of a solid fuel with limestone in the following molar ratios of limestone to said oxides: CaO:SiO.sub.2 =2.0, CaO:Al.sub.2 O.sub.3 =1.3-1.8, CaO:Fe.sub.2 O.sub.3 =1.0, at 1700.degree.-1900.degree. C. As a result, a melt is obtained containing calcium compounds: 2CaO.SiO.sub.2, 12CaO.7Al.sub.2 O.sub.3, CaO.Al.sub.2 O.sub.3, CaO.Fe.sub.2 O.sub.3. The melt is cooled and leached with soda solutions for extracting alumina. The sludge remaining after the leaching is suitable for Portland cement production. The invention enables a considerable enlargement of the range of starting products for aluminum and cement industries due to the use of the mineral component of solid fuels, an about twofold reduction of capital investments in the alumina production and reduction of the fuel consumption by 30-40%. | ||||||

| PURPOSE: A method for producing cement with paper sludge is provided to cut production cost of cement and prevent environmental pollution by using a large amount of paper sludge generated during paper production as materials of cement. CONSTITUTION: Paper sludge as a clayish material which is supplied from a paper factory is mixed with other materials including calcareous materials. The mixture is grinded to below the size of 100micrometer. Then, the grinded mixture is heated at a maximum temperature of 1500deg.C to generate clinker, an intermediate of cement. Plaster, an additive, is added to the clinker, which is minutely grinded to produce final product, cement. Additionally, this recycling of paper sludge can diminish disposal cost of wastes and contribute to the preservation of the environment. | ||||||

| The present invention relates to an apparatus for reusing metal mine waste and to a method for treating the latter, which effectively separate and recover metals which are precious minerals from metal mine waste, and reuse the residuals thereof as materials for cement, to thereby minimize the causes of environmental contamination and to maximize the reutilization of resources which might otherwise be treated as waste to achieve economical advantages. The apparatus of the present invention comprises a vibrating sorter for sorting metal mine waste, a kiln drier connected to the sorter to dry the metal mine waste discharged from the sorter at a temperature of 400°C or higher, a heat accumulator for supplying heat energy to the drier, a grinder for grinding the dried metal mine waste discharged from the drier, a specific gravity sorter which sorts the ground metal mine waste through a floating method by the specific gravity of metal minerals and non-metal minerals such as silica, lime, and the like; and a high frequency melting furnace for recovering metal from the metal minerals having a high specific gravity sorted by the floating method. The apparatus of the present invention further comprises a mixer for mixing the residuals of silica and lime ingredients, which are non-metal ingredients, sorted by the floating method, with a solidifying agent or the like to produce cement. | ||||||

| To make greater use of the possibilities offered by the recovery of waste material for the production of clinker, it is necessary to homogenize the solid residue resulting from the carbonization or partial combustion of the waste prior to its addition to the cement clinker, and to exclude part of the hot combustion gases laden with toxic material. The relatively large amount of waste matter having a calorific value offers considerable savings in primary energy needed for clinker production. | ||||||
