The Basic Refinery is a specialized version of the Refinery block. It is able to smelt Iron Ore and, as of v1.052, Nickel and Cobalt Ore, Silicon Ore, Magnesium Ore, and Stone, but it does so much more efficiently. It works 1.2x faster and takes 40% less power to smelt the same amount of ore.

In this process, the ore is mixed with special reagents and agitated by mechanical and pneumatic devices that produce air bubbles. As these rise through the mixture, the sulfide particles adhere to their surfaces and are collected as a concentrate containing 6 to 12 percent nickel.

When the material exits the mill, the iron ore is classified using cyclones or vibrating screens that separate fine and large particles. The large particles are diverted back into the crusher and the fine particles will undergo a spiral gravity separation process. 5.

First, the ore is treated with dilute sulphuric acid. This trickles slowly down through the ore, over a period of months, dissolving copper to form a weak solution of copper sulphate. The copper is then recovered by electrolysis. This process is known as SX-EW (solvent extraction/electrowinning).

The ore is again screened, with finer particles falls into the screen’s ceramic lined underpans and coarse particles are conveyed via an over belt magnetic separator to a Dense Medium Separation Drum. It is then laundered with a ceramic lined launder before again being screened by coarse waste and coarse iron drain and rinse screens. Refined coarse product can be sampled with a hammer sampler.
