Apatite Ore is an ore added by the Forestry mod. It is based on a phosphate mineral and is primarily used to create Fertilizer. Apatite Ore only generates on layers 64 and above and is therefore most commonly found in mountainous biomes, hills and exposed cliffsides. Apatite Ore spawns in very large veins of often over 20 blocks in size.
Apatite concentrate and effluent are treated with sulfuric acid hydrolyzing salts. Plant stocks are settled and water is conditioned by reacting with a strongly basic anion exchanger in carbonate form to a sulfate ion content of 50–90 mg / l, a carbonate equilibrium of 1–1.1 and a pH of 9.9-10.2. The treated water is transferred to grinding ...
