硫砒銅鉱を含む硫化銅鉱の浸出に関し、ヨウ化物イオン−鉄（ＩＩＩ）イオンを含む酸性溶液で、先ず硫砒銅鉱以外の硫化銅鉱を浸出し、ろ過後、浸出液と浸出が難しい硫砒銅鉱を含む浸出残渣を得て、ヨウ素酸化合物を有する希硫酸液を用いて、前記の浸出残渣から銅を浸出させる。例文帳に追加

In relation to leaching of copper sulfide ore containing enargite, copper sulfide ore other than the enargite is first leached in an acidic solution containing iodide ions-iron (III) ions and filtered; thereafter leaching residue containing leachate and enargite difficult to leach is obtained; and copper is leached from the leaching residue by using a dilute sulfuric acid solution containing an iodic acid compound. - 特許庁

黄銅鉱を含有する硫化銅鉱から銅を浸出するに際し、鉱石表面および浸出液中の微生物の生育を抑制し、かつ浸出液のｐＨを１．５以下に調整することを特徴とする、硫化銅鉱の浸出方法。例文帳に追加

In the method for leaching the copper-sulfide ore, when the copper is leached out from the copper-sulfide ore containing the chalcopyrite, the growth of microbe on the ore surface and in the leaching solution is restrained, and pH of the leaching solution is adjusted to be ≤1.5. - 特許庁

実操業レベルで汎用性ある条件で、難溶性で物理的分離も困難な硫砒銅鉱を比較的多量に含む、硫化銅鉱からなる銅精鉱から銅を効率よく浸出する方法を提供する。例文帳に追加

To provide a method of efficiently leaching copper from copper concentrate comprising copper sulfide ore containing a relatively large amount of enargite that is hardly-soluble and difficult to physically separate at an actual operation level and in a versatile condition. - 特許庁

黄銅鉱を主体鉱物とする高品位の銅鉱石を浮選し得られた銅精鉱を高温高圧化で浸出を行い、第２鉄イオンおよび硫酸を含有する銅浸出液を得て、低品位の銅鉱石に対するヒープリーチングまたはバットリーチングに前記銅出液を使用する。例文帳に追加

The copper concentrate, obtained by floating a high-quality copper ore comprising copper pyrite as a main mineral, is subjected to leaching under high-temperature and high-pressure conditions to obtain a copper leachate containing ferric ion and sulfuric acid which is used in heap leaching or vat leaching of a low-quality copper ore. - 特許庁

従来の処理技術より減少した費用で高い銅回収率を可能にする、銅含有物質から銅（特に黄銅鉱および輝銅鉱のような硫化銅から銅）を回収するための効果的かつ効率的な方法を提供すること。例文帳に追加

To provide an effective method for efficiently recovering copper from a copper-containing substance (particularly copper from a copper sulfide such as chalcopyrite and chalcocite), which realizes a high copper recovery rate at a reduced cost compared to conventional treatment techniques. - 特許庁

硫化銅鉱物を含む銅原料、特に黄鉄鉱を多く含有し、かつ硫化銅鉱物の含有が少ない低品位銅原料から、加圧容器中で酸素ガスを送入しつつ銅を浸出する方法において、該銅原料中のイオウの酸化を最小限に抑制しながら、銅を高収率で浸出する方法を提供する。例文帳に追加

To provide a method for leaching copper from a copper raw material containing copper sulfide mineral, particularly a low-grade copper raw material which is rich in pyrite and has a low content of copper sulfide mineral in a pressurized container by sending oxygen gas, by which the copper is leached in high yield while minimizing oxidation of sulfur in the copper raw material. - 特許庁
