根据鄂西铁矿石的特点进行了选矿药剂及相应的浮选和絮凝选矿工艺的研究，研制成功了RD-31捕收剂和DA-18选择性絮凝剂，采用磁选-脱泥-反浮选工艺流程，对武钢矿业公司科技处提供的鄂西铁矿混合矿样(WE-1样)进行

The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

结果表明：硫化矿的氧化溶解首先是磁黄铁矿，其次是铜的次生硫化矿，再次是黄铜矿，最后是黄铁矿；载金黄铜矿的氧化首先是铁从黄铜矿的晶格中氧化溶解出来，生成中间产物CuS2和CuS；较高的酸度和氯化钠浓度有利于单质硫的生成、三价铁的水解和铜的浸出，进而有利于金浸出率的提高。

The low Th and U content of the copper ores suggests that the Pb isotopic compositions of this type of ores are normal lead instead of radiogenic lead.

而且，铜矿石的低U、Th含量为该类铜矿石的铅是正常铅提供了合理的解释。

In sintering process, for melted mineral fines bind unmelted core ores when cooled, the self-intensity of binding phase in iron ores is one of the basic indexes to estimate sintered binding status.

在铁矿粉烧结过程中，熔化的矿粉在冷却过程中起着粘结周围未熔矿粉的作用，因此这一粘结相的自身强度是衡量烧结矿固结状况的重要指标之一。

The mineralization can be divided into two periods: the early mineralization including layered,layer parallel veined and brecciated ores,and the late mineralization including veinlets and veined ores.

矿床矿石硫化物硫同位素分析表明，早期矿化与晚期矿化具有不同的硫同位素特征：早期矿化硫化物的δ34S值(平均-4.31‰)明显小于晚期矿化硫化物的δ34S值(平均值为-1.83‰)。

The primary ores of the Laozuoshan gold deposit is a heavily disseminated and massive gold ores the main metallic mineral of which is pyrrhotite that account for approximately 11% occurring in migmatitic granite in disseminative and massive form and its gangue minerals take about 80% with quartz and feldspar as main minerals.
