Feb 01, 2017· It is important for the reader to understand that solvent extraction is only one unit process in a series of unit processes needed to win metal from ore. For this reason solvent extraction must be compatible with, and complimentary to, the leaching process which precedes it and the final metal recovery process which follows (Figure 1).extraction of titanium,Titanium is made by a batch process. In the production of iron, for example, there is a continuous flow through the Blast Furnace. Iron ore and coke and limestone are added to the top, and iron and slag removed from the bottom. This is a very efficient way of making something. With titanium, however, you make it one batch at a time.Gold Extraction & Recovery Processes,Feb 29, 2016· The ore body formation affects the mining method and the sequence of extracting different zones so that the beneficiation process can be effective.
