These 3 machines are used to get more raw materials from Ores.
The process starts with the Wasing Factory and produces 1-3 Dusts for each Ore, but you need to create the Fluid Sieving Machine first to create the Pink Slime Ingots.
Fluid Sieving Machine
Insert Fermented Ore Meat that you get from the Fermentation Station, and some
Sand,
and this machine will produce Dust of the type of Ore that you used.
But to get 
Pink Slime Ingots you need to insert
liquid Pink Slime, which you get from the Mob Slaughter Factory,
and an 
Iron Ingot.
Washing Factory
First connect this machine to power. Insert Liquid Meat that you get from the
Mob Slaughter Factory
and the Ore that you wish to wash. This process consumes the Ore but produces Raw Ore Meat which must be transferred over to the
Fermentation Station.
You can only insert Ores if a Dust variant of that material exists in your game. If you're playing ADDSynth's Science Modpack, you can insert Coal Ore, Iron Ore, Gold Ore, Lapis Lazuli Ore, Redstone Ore, Nether Quartz Ore, Sulfur Ore, Saltpeter Ore, Electrotine Ore, Certus Quartz Ore, and Aluminum Ore.
Fermentation Station
The Fermentation Station has additional requirements besides just being connected to power. There must be a heat source below the machine, such as Fire, Lava, or Magma Block, and a cold source on any other side. Water is commonly used as the cold source. I haven't tried Ice or a Snow block because I thought those would melt.
Once all requirements are met, insert the Raw Ore Meat you produced from the Washing Factory and this machine will turn it into Fermented Ore meat to be used in the Fluid Sieve Machine.
