WebMetal melting points vary greatly, mostly based on atomic weight and inter-atomic bond strength. Some metals are even liquid at room temperature. Mercury Symbol: Hg, Melting point: -37.89°F (-38.83°C) Mercury is a liquid at room temperature. Also known as quicksilver, it appears as a shiny silvery liquid that is much heavier than water. WebRefining using liquation method is the most suitable for metals with: 1. Low melting point 2. High boiling point 3. High electrical conductivity 4. Less tendency to be soluble in melts than impurities 15. The metal that is not extracted from its sulphide ore is 1. Aluminium 2. Iron 3. Lead 4. Zinc 16. ulcer with gangrene
