来源 :湿法冶金 | 被引量 : 0次 | 上传用户：jianxiaxjb

【摘 要】

：

研究了从铜冶炼黑铜泥中低温加压氧化浸出铜、砷,考察了温度、初始硫酸质量浓度、氧分压、液固体积质量比对铜、砷浸出的影响.结果表明:在初始硫酸质量浓度80 g/L、液固体积质量比10/1、温度120℃、氧分压0.3 M Pa、反应时间60 min条件下,黑铜泥中的铜、砷浸出率分别达99.5％ 和98.5％.浸出渣中锑和铋质量分数较原料(黑铜泥)富集8.5倍和14.9倍.

Steady-state solution of traffic flow on a simple road network

The steady-state traffic flow on a simply circled road network is analytically studied using the Lighthill-Witham-Richards(LWR) model.The network is typically composed of a diverging and a merging junction together with three connected road sections.At th

Numerical simulations of multi-layer-liquid sloshing by multiphase MPS method

In this paper,a multiphase moving particle semi-implicit (MPS) method is developed by introduction of various multiphase models into the original MPS method for single-phase flows,and is then applied to the numerical simulations of two-layer-liquid and th

Velocity and turbulence characteristics in an open channel with multi-row staggered vegetation patch

A staggered distribution of vegetation is very common in nature,which might significantly affect the flow structure.To investigate its impact,three rows of staggered vegetation groups are designed under seven different working conditions.The horizontal an

A simple analytical model to predict liquid unloading in the horizontal gas well

An accurate prediction of the critical gas velocity for the liquid loading is of great importance for operators to select the tubing diameter for the newly drilled gas wells,or to optimize the production rate for production wells.It is clear from previous
