Study on the Effect of Slimes on Flotation of Zinc Oxide Mineral;
矿泥对氧化锌矿物浮选行为的影响
The Determination for Eight Kinds of Elements in Wudalianchi Slime by Using Flame Atomic Absorption Spectrum;
火焰原子吸收法测定五大连池矿泥中八种元素
Test of reducing slime of oxidized zinc ore by using stirring mill has been carried out.
结果表明,搅拌磨能减少次生矿泥的产生,其原因主要是搅拌磨具有选择性破碎和自分级作用,粗粒级矿石受到的破碎作用力较强,而细粒级矿石受到较小的破碎作用力。
Studies of slime coating on coarse particles for Cu-Ni sulphide containing Pt and Pd had been made.
通过机理分析认为,造成矿泥罩盖的黏附力取决于:①矿泥颗粒的性质;②粗颗粒表面粗糙度;③镍黄铁矿表面氧化程度和"补丁"数量。
Through changing the structural parameter of classifying cyclone,and by mixed filter press and refuse slime,Nantong Coal Preparation Plant treated basically total refuse slime,and therefore increased the coal comprehensive utilization efficiency,and made a high economic benefit too.
通过改变分级旋流器的结构参数,利用煤泥、矿泥混合压滤等工艺,南桐选煤厂基本上消化了选矿矿泥,提高了煤炭的综合加工利用率,取得了较好的经济效益。
This method has settled the problem that the soft tailings mud can’t bear high stress.
0完全固结条件CU试验规律基础上,采用适度外延方法求出了不同固结度尾矿泥的总应力抗剪强度指标Ф,该方法解决了特软尾矿泥难以承受高应力得不到试验资料的难题,可供确定各类软土动力参数参考。
Consolidated undrained dynamic triaxial test of the saturated tailings mud under different degree of co- nsolidation and consolidation ratio conditions, is not only doing many work, but also very difficult to carry out a test of the high consolidation ratio because the tailings mud is very soft and its low strength.
饱和尾矿泥不同固结度和各种固结比条件下的固结不排水振动三轴试验,不但工作量大,而且由于尾矿泥很软,强度很低,难以进行高固结比试验。
