What is the approximate silver content of silver mine?

At present, the indicators of China's silver industry are as follows: cut-off grade Ag40 ~ 50g/t, industrial grade Ag 100- 120g/t, in other words, the silver content of silver ore is greater than Ag100g/t. ..

For associated silver ore, when the silver content is more than 5 ~ 10g/t, the calculated reserves are given. If the metallurgical properties of silver are good, it is sometimes reduced to 1g/t in copper-gold mines and 2g/t in lead-zinc mines.
