Minerals to Metals Part 10 Flashcards
What are the location of ore deposits related to and why?
The reactivity series, because highly reactive metals form soluble salts that dissolve in the ocean whereas un reactive metals are found native
What is the order of common metals from highest reactivity to lowest?
Potassium, sodium, calcium, magnesium, aluminium, zinc, iron, tin, lead, copper, silver, gold, platinum
What are the metals above carbon in the reactivity series?
Potassium, sodium, calcium, magnesium and aluminium
What is calcium found as?
Carbonates in limestone
What does magnesium form?
Silicates in rocks
What are aluminium, zinc and iron found as?
