Mineral Processor 3000

Mineral Processor 3000, or Mineral Processing, is the second-from-left shop that allows you to sell all the minerals you are carrying in one click. This is essential to obtain cash to buy anything else from the other shops.

Despite what its name indicates, you cannot process minerals directly into upgrades of the same material in Autobuy 2000. You can only sell minerals for cash, then buy those upgrades with cash.
