Add the lemon juice, the glass of water, the sugar, and the salt to a pitcher, and stir to leave the flavors to your desired level (keep in mind that you will add more water later, so if the mixture tastes a bit strong at this point, that might be best, all depending on your taste).
Add the mineral water, the mint leaves, ice, and stir.
Serve.
