To automate the collection of ore, use an Ore Extractor. You can place the extractor up against an ore block and it will consume energy to extract resources automatically. You can open the ore extractor control panel by pressing the 'Interact' key (default 'E'). This allows you to add energy to the machine from your suit, collect ore from its internal storage, and upgrade the machine. The starting extractors are significantly more resource efficient than super digging and can be left unattended.
