According to the results of floatation of artificial mixed mineral and characterization of SEM, the surface of ilmenite will be coated by micro-size titanaugite, and the increase of mineral surface hydrophobicity can result in the increase of attractive force between the two kinds of mineral particles.

通过人工混合矿浮选试验结果和扫描电镜检测验证，微细粒钛辉石会在钛铁矿表面发生罩盖现象；矿物表面疏水性增强，两种矿物颗粒间的引力相应增大。

Three main factors (viz. surface potential, particle size and surface wettability) that influence the interparticle interaction between titanaugite and ilmenite particles were investigated in detail through the calculation of DLVO theory, measurements of electrokinetic potential and contact angle, experiments of floatation and characterization of scanning electron microscope.

通过DLVO理论计算、动电位、接触角和扫描电镜检测及浮选试验，研究影响钛辉石和钛铁矿颗粒间相互作用的3个主要因素，即表面电性、颗粒粒径和表面润湿性。

Since Hanuman is the son of Vayu the Wind-god, he gets support in the form of free-floatation towards the destination.

自哈努曼的儿子Vayu风上帝，他会支持的形式，免费浮选走向目的地。

Combining the characteristic of mineral processing, several methods are introduced for controlling density of classing and value of grinding, and measurementing flotation liquid.

结合选矿生产过程的特点，在实际中采用模糊控制的方法，根据偏差的大小和变化率来控制磨矿旋流器入口浓度；采用控制均匀值的思想，保持球磨机给矿量平均值的稳定；还介绍了一种测量浮选槽液位的方法。

The paper presents that high pressure water jet comminuting technology was used for coal slurry pulverization,and then the comminuted slurry will be graded in a hydrocyclone,the fineness particles obtained from the over flow will be floated,and the coarseness particles from the under flow will be comminuted again.

介绍了采用高压水射流粉碎煤泥的技术，粉碎后的煤泥颗粒经水力旋流器进行分级，对溢流口得到的颗粒进行浮选，对底流口得到的颗粒再次粉碎。

The carbonaceous lead zinc ore in Inner Mongolia is very large in reserve,but it contains a high level carbon,which interferes with the selective flotation of these ores,making the selective process target very low and economic benefit poor.In recent years,the decarbonizing technology has been greatly improved that provides enough reliable information to exploit these ores

近年来 ，在内蒙古地区先后发现了几处大型含碳铅锌多金属矿床，但矿石中的高含碳量已成为制约铅锌矿开发利用的主要因素，以至于有些矿床至今未被开发利用，除碳已成为含碳铅锌多金属矿床开发利用的关键由于碳对浮选药剂的选择与消耗、工艺流程的制定和技术经济指标都有显著

Meanwhile, we discuss the deinking mechanism: solvent treatment dislodges most ink particles from the fibers, then ultrasonic treatment scatters detached ink particles which are separated from the stock by following washing and floatition process, so that deinking efficiency is improved greatly.

同时 我们对其脱墨机理进行初步研究，可以这样认为：先用溶剂预处理，将大部分油墨粒子从纤维上分离下来，然后再辅以超声波的作用，将分离下来的油墨粒子打碎，在后面的浮选洗涤过程中将这些打碎成很细小的油墨粒子去除，从而大大地提高了混合办公废纸的脱墨效果。

The experimental results showed that the influence of the effect for changing the amount of emulsified reagent and forther.

研究了改变捕收剂用量和起泡剂用量等工艺措施对浮选效果的影响。

"You can obviously find some parts of China that frothed up at the end of last year into this year," said Anthony Michael, head of Asian fixed income for Aberdeen Asset Management.

&你可以明显发现中国的一些部件浮选在去年一年最终这个年，&安东尼说迈克尔，为香港仔的亚洲资产管理固定income head。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
