In this paper, the effect of various main factor on the shear-flocculation flotation of ultrafine wolframite particles was investigated. For ultrafine wolframite particles(—5μm), the recovery of wolframite in shear-flocculation flotation is 80%, instead Of 50% in conventional flotation. For artificial mixtures of ultrafine wolframite (-5μm) and quartz(—10μm) with the head grade (WO_3) of 12.18%, the concentrate grade (WO_3) and recovery of wolframite in shear-flocculation flotation are 39.29% and 82.56% respectively,...

For artificial mixtures of ultrafine wolframite (-5μm) and quartz(—10μm) with the head grade (WO_3) of 12.18%, the concentrate grade (WO_3) and recovery of wolframite in shear-flocculation flotation are 39.29% and 82.56% respectively, instead of 30.14% and 58.92% respectively in conventional flotation.The mechanism of shear-flocculation flotation of ultrafine wolframite was studied through instrument analysis and theoretical calculation on the basis of hydromechanis and colloid chemistry. The mechanism studied suggestes that:(1) In shear-flocculation flotation operation of ultrafine wolframite particles, the main aim of high speed stirring is to increase shear rate of fluid, causing high collision energy to overcome the repulsive energy barrer existing between ultrafine wolframite particles.(2) The van der Waals attractive interaction energy is increased remarkably by the hydrophobic association of sodium oleat adsorbed on the surface of wolframite particles, so that the tough, high strength and flocs are formed, the particles size D_(80) of wolframite particles is increased from 4.1μm to 8.5μm and the rate of shear-flocculation flotation is 4.1 time the rate of conventional flotation.

本研究详细考察了微细拉黑钨矿剪切絮凝浮选的主要影响因素。对于-5微米黑钨矿纯矿物,剪切絮凝浮选可使其浮选回收率由常规浮选的50%提高到80%;对于原矿品位(WO_3)为12.18%的黑钨矿(-5微米)—石英(-10微米)人工混合矿,剪切絮凝浮选可使精矿品位(WO_3)由常规浮选的30.14%提高到39.28%,回收率由常规浮选的58.92%提高到82.56%。通过仪器分析与理论计算,研究了剪切絮凝浮选的主要机理。在剪切絮凝浮选过程中,强烈搅拌的主要目的在于提高运动流体的剪切速度,从而增加微细粒黑钨矿粒子间碰撞作用能,使之足以克服粒子间存在的斥力能峰;长烃键捕收剂加入的主要作用在于黑钨矿粒子表面吸附了捕收剂以后,可显著提高黑钨矿粒子间吸引作用能,使碰撞能足以克服斥力能峰时导致黑钨矿粒子间产生絮团现象,形成结构密实、强度高的球形絮团,矿物粒度分布的d_(80)由4.1微米增加到8.5微米,浮选速度增加4.1倍。

Specimens of various materials were ion-nitrided in different atmospheres and at different ionic energy levels. A collision-dissociation model of ion-nitriding was proposed in this paper based on the results of ion-nitriding tests and calulations of the densities of ions and neutral particles in the cathode fall region, together with the analysis of collision process and cathode sputtering effects. In ionnitriding there are possibly several processes of nitrogen atom migration from gas phase to solid phase, but ion-nitriding is achieved primarily due to penetration of active nitrogen atoms produced by collision-dissociation. The energy conditions of N_2, NH_1 and N_2-H_2in collision-dissociation were analysed and the amount of active nitrogen atoms was calculated semi-quantitatively. The calculated data were in agreement with the results of the nitriding tests. The effects of H_2 on collision-dissociation as well as transfer of the energy heating the cathode in ion-nitriding were also discussed.

本文根据在不同气氛、不同离子能量条件下离子氮化的试验结果,分析了在阴极位降区中的离子浓度和中性粒子浓度,以及粒子间的碰撞过程、阴极溅射数量等,提出了离子氮化的碰撞离解模型;在离子氮化中,氮从气相迁移到固相,虽然存在着几种可能机构,但主要是通过碰撞离解产生大量活性氮原子渗入工件而实现的。碰撞离解有两种情况,其一,高速正离子与N_2,NH_j作非弹性碰撞使后者离解;其二,在与高速正离子作弹性碰撞中获得足够高能量的N_2或NH_j分子相互碰撞或与阴极碰撞瞬间亦能离解产生活性氮原子。文中分析了碰撞离解的能量条件,提出了相应的计算方法,计算数据与氮化结果相吻合。还阐明了氢在碰撞离解中的作用以及阴极加热的能量传输机构。
