the important role that pH measurement serves to control the end product quality. The Sulfate & Chloride Processes There are two processes used to leach titanium from ore: the chloride process and the sulfate process. The chloride process uses chlorine gas (Cl 2) and coke (C+) at elevated temperature to create titanium tetrachloride (TiCl 4). Sec-

Gypsum is neutral in pH, and since it has no carbonate ion as part of its makeup, it will not neutralize acidity. However, it is much more soluble than most lime products (about 200 times as soluble), so it does make a very good source for soluble calcium and sulfate. In other words, applying gypsum to the soil will raise the calcium …
