山東省焦家金礦的金賦存狀態(tài)
摘要：采用顯微鏡和掃描電子顯微鏡研究了山東省焦家金礦的金賦存狀態(tài).研究發(fā)現(xiàn),該礦石中載金礦物有黃鐵礦、黃銅礦、脈石礦物、閃鋅礦和方鉛礦.在硫化礦中金粒占77.12％,脈石中金粒占22.88％.金的賦存狀態(tài)有裂隙金、包裹金和晶隙金,裂隙金占60.28％,包裹金占21.63％,晶隙金占18.09％.金礦物的形態(tài)主要有球狀、三角形、矩形、條狀和不規(guī)則形狀.焦家金礦石中金礦物的粒度范圍較大,大的顆粒達(dá)到100 μm,小的'金顆粒只有3-5 μm,其中大于0.104 mm粒級的金顆粒占1.50％,0.074～0.104 mm粒級的金顆粒占5.26％,0.043～0.074 mm粒級的金顆粒占23.31％,0.037～0.043 mm粒級的金顆粒占3.76％,小于0.037 mm的金顆粒占64.29％.焦家金礦石中金礦物有自然金、銀金礦、自然銀、含鐵自然銀、金銅礦和螺硫銀礦.其中,銀金礦是最重要的金礦物,占71.56％.金銀礦物平均成色為641.24‰.Abstract：The microscopy and scanning electronic microscopy(SEM)were used to study the gold occurrence of Jiaojia gold mine,Shandong province.The results show that the gold-bearing minerals are composed of pyrite,chalcopyrite,gangue,sphalerite and galena.77.12％ of gold minerals are the sulphides and 22.88％ are the gangues.The gold occurrence is composed of 60.28％ fissure gold,21.63％ inclusion gold and 18.09％ crystal fractured gold.The morphology of gold mineral is composed of sphere,triangle,rectangle,strip and erose.The Jiaojia gold mineral owns large grain size range from 3-5 μm to 100 μm.1.5％ of gold grains is more than 0.104 mm,5.26％ is 0.074-0.104 mm,23.31％ is 0.043-0.074 mm,3.76％ is 0.043-0.037 mm and 64.29％ is less than 0.037 mm.The occurrence of gold mineral is composed of native gold,electrum,native silver,iron-bearing native silver,goldcuprid and acanthite.Electrum is the most important mineral,accounting for 71.56％.The average quality is 641.26‰ for gold and silver mineral. 作者： 楊洪英 王思惠 宋襄翎 潘顥丹 馬鵬程 Author： YANG Hong-ying WANG Si-hui SONG Xiang-ling PAN Hao-dan MAPeng-cheng 作者單位： 東北大學(xué)材料與冶金學(xué)院,沈陽,110004 期 刊： 中國有色金屬學(xué)報（英文版） ISTICEISCI Journal： Transactions of Nonferrous Metals Society of China 年，卷(期)： 2011, 21(9) 分類號： P618.51 關(guān)鍵詞： 金礦 金賦存狀態(tài) 載金礦物 金礦物 Keywords： gold mine gold occurrence gold-bearing mineral gold mineral 機(jī)標(biāo)分類號： P61 P57 機(jī)標(biāo)關(guān)鍵詞： 山東省 焦家金礦 金賦存狀態(tài) 金顆粒 mineral 載金礦物 scanning electronic microscopy gold occurrence native 粒級 掃描電子顯微鏡 自然 銀金礦 裂隙金 金礦石 金的賦存狀態(tài) 包裹金 不規(guī)則形狀 grain size 金銀礦物 基金項目： the National Natural Science Foundation of China，the National High-Tech Research and Development Program of China，the National Support Program of China during the 11 th Five-Year Plan Period 山東省焦家金礦的金賦存狀態(tài)[期刊論文] 中國有色金屬學(xué)報（英文版） --2011, 21(9)楊洪英 王思惠 宋襄翎 潘顥丹 馬鵬程采用顯微鏡和掃描電子顯微鏡研究了山東省焦家金礦的金賦存狀態(tài).研究發(fā)現(xiàn),該礦石中載金礦物有黃鐵礦、黃銅礦、脈石礦物、閃鋅礦和方鉛礦.在硫化礦中金粒占77.12％,脈石中金粒占22.88％.金的賦存狀態(tài)有裂隙金、包裹金和晶隙金...【山東省焦家金礦的金賦存狀態(tài)】相關(guān)文章：
