Abstract:
Disclosed is a method of detoxifying asbestos by using a room-temperature recrystallization scheme. The method includes heat-treating a rock or slate containing asbestos; and putting the heat-treated rock or slate in an aqueous solution, to which organic acid is added, to allow the heat-treated rock or slate to react with the aqueous solution having the organic acid.
