How are low reactivity metals extracted
WebThe processes used for removing the gangue from the ore are based on the differences between the physical or chemical properties of the gangue and the ore. Different separation techniques are accordingly employed. 1. Extracting Metals Low in the Reactivity Series. Metals low in the activity series are very unreactive. Web10 de mar. de 2015 · The metal reactivity series is a commonly taught concept in chemistry, placing the metals, as its name suggests, in order of reactivity from most reactive to least reactive. It’s also a useful tool in predicting the products of simple displacement reactions involving two different metals, as well as providing an insight into …
