There are two types of phosphate acid production processes, i.e., wet and furnace processes. Each process has its own advantage and disadvantage. This research was concentrated on wet process as it's more economical in industrial scale and it only uses simple equipment. In this process solution of sulfuric acid (H2SO4) was added into phosphate rocks. The reaction produced phosphate acid and calcium sulfate. The concentration of sulfuric acid, temperature and period reaction were varied. Extraction of phosphate oxide (P2O5) from phosphate rock can be optimized by manipulation which may affect the reaction. The result showed that optimum condition of the process were obtained at 8.2 operation hours, sulfate concentration of 27,7%, temperature of 81,1drajatC. The result obtained was 23,38% phosphate acid.
