Abstract

Ni extraction from laterite ore has progressively intensified via various hydrometallurgical methods. One of the by-products of the leaching process is Mn, which can increase the resilience of this metal supply on the market. By observing the effects of the laterite roasting temperature and the effects of the Mn leaching temperature and duration, we can obtain insight into the coextraction of Mn from laterite leaching. Roasting was carried out at 280 and 610 °C, whereas leaching experiments were conducted at 30–90 °C for 0–120 min. The leaching efficiency of Mn increased with increasing roasting temperature, leaching temperature, and leaching duration. The optimum leaching conditions were obtained using a 280 °C roasted sample at a leaching temperature of 90 °C for 90 min. Under these conditions, the Mn leaching efficiency reached 95.5%. Roasting also affects the Mn leaching kinetics parameters, and increasing the roasting temperature results in an increase in the Ea value of the leaching process.

热处理对红土锰矿浸出动力学的影响

通过各种湿法冶金方法，红土矿石中镍的提取日益加强。浸出过程的副产品之一是锰，这可以增加市场上这种金属供应的弹性。通过观察红土焙烧温度、Mn浸出温度和浸出时间的影响，可以深入了解红土浸出Mn的共浸过程。焙烧温度分别为280℃和610℃，浸出温度分别为30℃和90℃，浸出时间分别为0 ~ 120 min。随着焙烧温度、浸出温度和浸出时间的增加，Mn的浸出效率提高。在280℃焙烧样品、90℃浸出、90 min浸出条件下，Mn浸出率达到95.5%。焙烧对Mn浸出动力学参数也有影响，焙烧温度升高导致浸出过程Ea值升高。

期刊介绍： Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc. Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
