(Originais Teachy 2023) - Question Medium of Chemistry

A soil sample was collected in a region where the presence of a valuable metal is suspected. Initial analyses indicated that the soil is a mixture of sand, clay, water, organic matter, and small particles of the metal. A group of Chemistry and Geography students proposed to study the properties and classification of the substances present in this sample. Considering the soil as a mixture and the pure substances present in it, such as the metal, write an interdisciplinary text that: 1. Explain which separation methods could be used to isolate the metal sample from the soil, detailing the chemical principle of each method. 2. Discuss the importance of knowledge about the properties of substances and separation methods for geographical study and for the potential economic exploitation of the region where the soil was collected.
