pyrite concentrateとは 意味・読み方・使い方

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.例文帳に追加

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。 - 特許庁

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.例文帳に追加

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。 - 特許庁
