銅鉱体の英語

硫化銅鉱中の硫黄の酸化に過塩素酸などの酸化剤をを用いて、硫化銅鉱を過塩素酸を含む無機酸たとえば塩酸混合溶液により加熱焙焼して、硫黄を単体硫黄として固定し、焙焼生成物を水で浸出して銅及び／又は金を抽出する分離する。例文帳に追加

This method comprises employing an oxidant for oxidizing sulfur in the chalcocite, such as perchloric acid, heating and calcinating the chalcocite in an inorganic acid solution containing perchloric acid such as a mixture solution of hydrochloric acid, fixing sulfur as elemental sulfur, soaking the calcinated product in water, and extracting and separating copper and/or gold. - 特許庁

簡便で、低コストで、かつ安全環境面で特別な配慮を必要としない黄銅鉱を主体とする含銅硫化物からの銀の浸出方法の提供を課題とする。例文帳に追加

To provide a method for easily leaching a silver from a sulfide containing copper consisting essentially of chalcopyrite, at a low cost without needing a special consideration with respect to the safety environment. - 特許庁

より具体的には、本発明は、加圧浸出および直接電解採取を、浸出、溶媒／溶液抽出、および電解採取操作と組み合わせて用い、黄銅鉱含有鉱石から銅を回収するための実質的な酸の自己生産工程に関する。例文帳に追加

More particularly, the present invention relates to a substantially acid-autogenous process for recovering copper from chalcopyrite-containing ore using pressure leaching and direct electrowinning in combination with a leaching, solvent/solution extraction and electrowinning operation. - 特許庁

より具体的には、本発明は浸出、溶媒／溶液抽出および電解採取作業と組み合わせて加圧浸出および直接電解採取を使用して、黄銅鉱含有鉱石から銅を回収する、実質的に酸が自生するプロセスに関する。例文帳に追加

More particularly, the present invention relates to a substantially acid-autogenous process for recovering the copper from chalcopyrite-containing ore using the pressurized leaching and directwinning in combination with leaching, solvent/solution extraction and electrowinning operation. - 特許庁

銅精鉱の処理方法は、黄銅鉱（ＣｕＦｅＳ_２）を主体とする銅精鉱を硫化した後に摩鉱し、５０％粒子径が５μｍ〜１０μｍの摩鉱精鉱を浮遊選鉱処理することによって、Ｃｕ品位の高い精鉱とＦｅ品位の高い精鉱とに分離する分離工程を含む。例文帳に追加

The method for treating copper concentrate includes a separation step in which copper concentrate mainly comprising copper pyrite (CuFeS_2) is sulfurated and then ground, and the ground ore having a 50% particle diameter of 5 to 10 μm is subjected to floatation sorting treatment to separate the ground ore into a concentrate with a high Cu grade and a concentrate with a high Fe grade. - 特許庁

過去には、市況にとらわれず銅鉱山の権益を戦略的に獲得し自主開発比率を向上させてきたように、他の資源についても、官民一体となった取組を通じて、事業活動の安定化や価格競争力強化に直結する自主開発比率を向上させる投資が、円高等を背景に積極的に行われることが期待されている。例文帳に追加

In the past, Japan raised the ratio of self-development by obtaining rights to exploit and run copper mines as a strategic initiative regardless of market conditions. It is also desirable that with regard to other resources, the public and private sectors work together to make active investments against the background of a strong yen, in order to raise the ratio of self-development, which directly contributes to stable project management and enhancement of price competitiveness. - 経済産業省
