    This is an advantage with many ores in respect that the gold is more readily accessible to the solutions but on the other hand the product is more difficult to leach. The output in dry crushing is much lower than in wet crushing by stamps and the cost per ton of ore is stated to be from 50 to 100 per cent. more.
