The content of mineral elements in ripe fruits of M.sieversii from 78 seedings at Mohe Town,Gongliu Country were analyzed using Atomic Absorption Spectrophotometer.The results indicated that M.sieversii seedings presented considerable genetic variations in content of mineral elements with the range of variation coefficients from 24.2% to 54.0%.So it has large potential for further selection.Four elite seedlings were selected,namely large fruit type,high Ca content type,high Zn content type and high damascenone content.As the predominant component of Ily wild fruit tree forest,Malus sieversii had occupied an area of 9300ha.But the inherent reproduction system of M.sieversii and genetic diversity of the species were destructed in different degrees,as a result of farming assart,over grazing and damage by Agrilus mali.

上述结果支持&新疆野苹果可能是栽培苹果祖先种&的结论；②对巩留县莫舍乡的新疆野苹果78个实生株系果肉组织Ca、Mg、Fe、Zn、Cu、Mn6种矿质营养元素进行测定的结果表明，每种矿质元素含量单株间差异显著，变异系数在24.2％～54.0％，遗传多样性丰富，进一步选择的潜力很大；③根据新疆野苹果果实形态、香味物质和矿质元素含量等的测定结果，初步筛选出了大果型、高钙型、高锌型和大马酮型等4个特异性状单株；④调查发现，由于农田开垦、过度放牧以及苹果小吉丁虫的蔓延危害，目前伊犁野果林面积逐年减少，野苹果固有的繁育体系和遗传多样性受到不同程度的破坏。

Based on the above research, we analyzed regional metallogenic conditions from geology, geophysics and geochemistry. Considering regional strata, some source beds with ore-bearing strata controlled apparently metallogenesis. The strata contained hydrothermal siliceous rock or siliceous albitite ether formed some favorable source beds and established substantial foundation for later diplogenetic metallogenesis e.g.

从区域地层上来看，含特殊层位的矿源层对成矿有明显的控制作用，其中含热水沉积成因的硅质岩或硅质钠长质岩的地层或形成有利的矿源岩，为后期叠生成矿奠定物质基础，或直接形成工业矿床；另外，区内黑色页岩（包括碳质板岩、碳质泥岩、碳质页岩和含碳钙质板岩等）也是很好的矿源层。

The influence of class if ying equipment and circulating loading on the closed-circuit grinding for prep aration of primary ore plup feed in Bayer Process and especially the importance of its circulating loading in ore grinding are discussed.

根据我国一水硬铝石难磨的特点研究了适宜于一水硬铝石特点的拜尔法原矿浆制备磨矿回路，明确提出格子磨加旋流器一段闭路磨矿流程是目前拜尔法原矿浆制备工艺的最佳选择，该磨矿回路已在山西铝厂工业应用且取得了良好的技术经济效益。

磨矿分级自动控制发展现状在选矿行业中，磨矿分级生产过程是一个重要的生产环节，磨矿分级自动控制也是最难解决的课题。

According to the mineral analysis of high silicon zinc oxide ore from Guangxi province, most of zinc exists in matters of zinc silicate and calamine.

通过对广西某地高硅氧化锌矿矿物分析可知，矿物中的锌主要以硅锌矿和异极矿的形式存在。

Cu~2+ can activate marmatite . Eh of pulp has great effect on the buoyancy of them. New inhibition regeants named CSU-1 can inhibitmarmatite buoyancy. In high pH value and low Eh, use lot of calcareousness, marmatite can separated from pyrrhppite easily in their concentrate mixture.

少量的Cu~(2+)可强烈地活化铁闪锌矿；矿浆电位对三种矿物的浮选有明显的影响；新型抑制剂CSU-1可有效地抑制铁闪锌矿；采用高石灰用量、高pH矿浆和低电位环境，实现混合精矿中铁闪锌矿与磁黄铁矿的分离。

"The reason why Carajas ore powder prices are not the same, mainly due to European prices in 2007, the Carajas mineral powder mineral powder south than the original high 3.2 cents, while Asia only 1.1 cents. After 2008, Asia and Europe than in the southern Powder Powder cards are 6.19 cents higher."

&之所以卡拉加斯粉矿价格也不尽相同，主要是由于2007年欧洲的价格，卡拉加斯粉矿矿石粉比原来的南高3.2美分，而亚洲只有1.1美分。2008年以后，亚洲和欧洲比南部粉粉末卡是6.19美分。&

According to analysis to poisonous grit mineral character,discussion about how to conquer arsenic in vulcanization ore and the investigations of much cassiterite metal vulcanization ore , much cassiterite metal vulcanization ore is a new kind of reagent,it is effective in reducing arsenic.

通过对毒砂矿物性质的分析，探讨硫化矿降砷及锡石多金属硫化矿选别试验，得出锡石多金属硫化矿浮选降砷的有效抑制剂为TS-1新药剂。

The mathematical relationships among mixed layer thickness, ore recovery and waste dilution against drawpoint spacing, volume per drawing, cut-off waste dilution and level interval are studied in details. It shows that the contact face between ore and waste as a ideal interface is incorrect during drawing.

以二次回归正交放矿计算机仿真实验为研究手段，以单一采场放矿为研究对象，详细地阐明了混杂层厚度、矿石回贫指标与漏斗间距、一份放出量、截止废石混入率及阶段高度之间的数学关系；研究指出：在放矿过程中，将崩落矿岩接触带视为一理想界面是不正确的。
