Zinc is more reactive than tin. Tin only reacts with very strong acids. However, zinc can react with simple acids found in food. Hence, in order to prevent food poisoning, the food cans are coated with a cheap, less reactive metal like tin.
What Are The Biggest Industries In Bulgaria? - WorldAtlas
Bulgaria is among the world’s largest producers of zinc, copper, and lead. Black coking coal reserves have also been discovered in Kremikovtsi near Sofia. About 40 coal basins have been identified through exploration ventures; amounting to three billion tons worth of coal reserves that are mainly lignite.
