COMPOSITION AND PROCESS FOR REDUCING OR PREVENTING METAL AND ACID CONTAMINATION IN ROCK DRAINAGE
专利汇可以提供COMPOSITION AND PROCESS FOR REDUCING OR PREVENTING METAL AND ACID CONTAMINATION IN ROCK DRAINAGE专利检索，专利查询，专利分析的服务。并且The formation of contaminants in drainage from waste rock or tailings is reduced or prevented by contacting the waste rock or tailings with an organic or inorganic sulfur compound in combination with a neutralizing agent, a fixating agent or a neutralizing agent and a fixating agent. When an organic or inorganic sulfur compound is used with the neutralizing agent or fixating agent, the amount of neutralizing agent and/or the amount of fixating agent required to reduce or prevent the formation of contaminants in drainage from waste rock or tailings is substantially reduced. The amount of sulfur compound applied to the waste rock or tailings can be about 1 % to 5 % by weight and the amount of neutralizing agent and/or fixating agent applied to the waste rock or tailings can be about 1 % to about 15 % by weight, based on the weight of the waste rock or tailings. The organic or inorganic sulfur compounds are those having a sulfhydryl group or an ionized sulfhydryl group or a sulfur compound which is capable of producing a sulfhydryl group or an ionized sulfhydryl group.，下面是COMPOSITION AND PROCESS FOR REDUCING OR PREVENTING METAL AND ACID CONTAMINATION IN ROCK DRAINAGE专利的具体信息内容。
