I want to know the maximum buy or sell lot for one transaction for copper mini.

I guess you saw this on the contract specification on MCX. 

Though as per contract specification, you can place 280 lots ( 250kg is 1 mini copper, so 1 MT = 4 lots, 70 MT = 280 lots).

But however since there is a risk of execution, how many lots you can place in a single order is actually determined by the broker. So for example, we at Zerodha allow you to trade 100 lots of Copper mini at one time.
