1Beneficiation of the gold bearing ore by gravity and flotation显示文摘Gold concentration usually consists of gravity separation, flotation, cyanidation, or the combination of these processes. The choice among these processes depends on the mineralogical characterization and gold content of the ore. Recently, the recovery of gold using gravity methods has gained attention because of low cost and environmentally friendly operations. In this study, gold pre-concentrates were produced by the stepwise gravity separation and flotation techniques. The Knelson concentrator and conventional flotation were employed for the recovery of gold. Gold bearing ore samples were taken from Gümüshane Region, northern east part of Turkey. As a result of stepwise Knelson concentration experiments, a gold concentrate assaying around 620 g/t is produced with 41.4wt% recovery. On the other hand, a gold concentrate about 82 g/t is obtained with 89.9wt% recovery from a gold ore assaying 6 g/t Au by direct flotation.Alim Gül Olga Kangal Ayhan A.

2一种人工天青石矿的浮选及夹带行为的统计分析(英文)显示文摘研究浮选参数对泡沫浮选脉石回收率的影响,测试了pH=10时起泡剂类型和捕收剂用量对浮选性能的影响。采用方差分析了测试结果。在用油酸钠作捕收剂的情况下,亲水性矿物的浮选主要是由于Ca+2离子对石英的活化产生的疏水性而导致的夹带作用所引起的;夹带和矿泥包裹层对浮选也有一定的影响。在浮选产物中脉石的夹带程度随着矿石颗粒粒度的减小而增加。实验结果表明,通过增大捕收剂用量、缩短浮选时间,可以减小水流夹带作用,提高浮选的选择性。Taki GüLER ünal AKDEMR 2012Transactions of Nonferrous Metals Society of China2012,22,1:5
3Mass Balance Modeling for Electric Arc Furnace and Ladle Furnace System in Steelmaking Facility in Turkey显示文摘In the electric arc furnace (EAF) steel production processes, scrap steel is principally used as a raw material instead of iron ore. In the steelmaking process with EAF, scrap is first melted in the furnace and then the desired chemical composition of the steel can be obtained in a special furnace such as ladle furnace (LF). This kind of furnace process is used for the secondary refining of alloy steel. LF furnace offers strong heating fluxes and enables precise temperature control, thereby allowing for the addition of desired amounts of various alloying elements. It also provides outstanding desulfurization at high-temperature treatment by reducing molten steel fluxes and removing deoxidation products. Elemental analysis with mass balance modeling is important to know the precise amount of required alloys for the LF input with respect to scrap composition. In present study, chemical reactions with mass conservation law in EAF and LF were modeled altogether as a whole system and chemical compositions of the final steel alloy output can be obtained precisely according to different scrap compositions, alloying elements ratios, and other input amounts. Besides, it was found that the mass efficiency for iron element in the system is 95.93%. These efficiencies are calculated for all input elements as 8.45% for C, 30.31% for Si, 46.36% for Mn, 30.64% for P, 41.96% for S, and 69.79% for Cr, etc. These efficiencies provide valuable ideas about the amount of the input materials that are vanished or combusted for 100 kg of each of the input materials in the EAF and LF system.smail Ekmeki Ya ar Yetisken nal ■amdali 2007Journal of Iron and Steel Research(International)2007,14,5:4
