1第2章细菌冶金工艺矿物学Microbio-hydrometallurgy22.1矿物特性在细菌冶金中的地位2.1.1概述细菌冶金工艺过程的主要问题:周期长,影响工艺的因素多,难于控制。问题的实质是参与细菌冶金过程反应的双方——细菌和矿石中的硫化物都是复杂多变的。细菌冶金过程反应速度取决于硫化物矿物学性质的观点:矿石中硫化物是天然结晶形成的,其矿石的工艺矿物学性质,诸如化学成分、晶体结构、元素赋存状态等方面都是很复杂的,...
第一章,着重概念,:晶体,内部质点在三维空间呈周期性重复排列的固体。显晶质,借助于肉眼或一般放大镜能分辨出结晶颗粒者。隐晶质,用一般放大镜无法分辨出结晶颗粒者。非晶质体,是内部质点在三维空间不作周期性重复排列的固体。本质性的区别,晶体既具短程有序,近程规律,,也具长程有序,远程规律,,非晶质体、液体只有近程规律,而无远程规律,气体既无远程规律,也无近程规律。准晶体,是内部质点的排布具长程有序,远程规律,,但不具有...
