  Nickel: smelting, producingMetalpedia

  In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the SherrittGordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt .

  Nickel Ore | Space Engineers Wiki | Fandom

  Nickel Ore is a common, naturally occurring ore found in asteroids and terrestrial planets. It has a shiny yellowish texture, almost like pirite/fake gold. Nickel can be processed in a Refinery to produce Nickel Ingots at a 40% ratio. Which is to say, 1000 kg of ore will produce 400 kg of ingots. Using a Refinery, 749 kg of Nickel Ingot can be produced per hour, without Speed or .

  The Mining Process

  Gold at Macraes is known as 'refractory ore', which means it is ultrafine and resistant to the typical cyanide leach process, typical of most gold processing plants. This refractory nature of the ore led to inefficiencies recovering the gold from ore in the past. The ore now goes through a threestage processing cycle to ensure the gold is economically recovered from the ore.
