In the world stone trade, the proportion of granite products has been increasing, and it is now at the climax of development. At present, the world’s total stone production is about 23 million tons, of which granite is 8.3 million tons, accounting for about 36% of total output, of which France is 3.8 million tons, Spain is 1.5 million tons, Soviet Union is 1.2 million tons, Italy is 1.5 million tons, and Norway44 Ten thousand tons.
