And finally , for the denver report of 2007 , here is jorge from patagonia minerals , who had even more amazing pieces of the hematite pseudomorphs after magnetite from argentina than we ' d seen before , including this stunner which looks like some kind of ' star wars ' ray gun 最后，为了2007年丹佛展会的报告，这里是来自巴塔哥尼亚的豪尔赫，他有很多奇异的阿根廷赤铁矿假象和磁铁矿，以前我们从未见过的，包括这个看起来像某种形式的'星球大战'射线枪的尤物。
The beheviour of four low - molecule weight organic acid lactic acid , hydroxy - acetic acid , mercapto - acetic acid , glyconic acid as iron - containing silicate - aegirines depressants on the hematite direct flotation is investigated in this paper . the results of flotation tests with pure minerals , artificial mixture of minerals and naturally occurring ore show this depressants have good selectivity in flotation . the flotation separation of hematite from aegirine is achieved successfully with the four depressants 本文研究了四种小分子有机酸抑制剂乳酸、羟基乙酸、巯基乙酸、葡糖酸在赤铁矿正浮选中对含铁硅酸盐脉石霓石的抑制行为，纯矿物、人工混合矿与实际矿石浮选实验均证明了它们具有良好的选择性抑制作用，可以成功地实现赤铁矿与霓石的浮选分离。
" a recent cleaning operation by laser revealed traces of haematite , egyptian blue and malachite - azurite green - blue on the sculptures of the western frieze , " senior archaeologist evi papakonstantinou - zioti told afp . while archaeologists had found traces of the first two colours elsewhere on the temple years ago , the malachite - azurite colouring was only revealed in the latest restoration process , papakonstantinou - zioti said 日前她在接受法新社记者采访时说： “最近我们在使用激光对神庙进行清洗工作时发现，神庙西部的雕刻上残存有赤铁矿红色埃及蓝一种含有铜钙硅的浅蓝色颜料以及孔雀石蓝铜矿蓝绿色的痕迹。 ”
He found that the red pigment proved to be iron oxide , hematite ; a yellow consisted of clay containing iron or yellow ochre ; a blue color was a finely powdered glass ; and a pale blue was a copper carbonate , probably azurite ; green were malachite ; black was charcoal or boneblack ; gray , a limestone mixed with charcoal ; and a quantity of pigment remaining in a paint pot used in the decoration , contained a mixture of hematite with limestone and clay 他发现红颜料是铁的氧化物赤铁矿；黄色颜料由含有铁或黄赭色粘土组成；蓝颜色为细微的玻璃粉；而普蓝就是碳酸铜，或许是蓝铜矿；绿颜料为孔雀石；黑色为木炭或骨黑；灰色，石灰石混合木炭而成；而一些颜料残留在用于彩绘装饰的颜料瓶里，含有赤铁矿与石灰石及粘土的混合物。
