SESSION #1 – Which chemical products are required (input and output) to extract the raw material indium for an LCD screen?

Our research deals with the material indium, an important metal for LCD displays, and the chemical products that are necessary as input and output for the extraction of indium. Our focus was on how a small amount of the metal is extracted from a large mass of soil.
