Britain's mining and quarrying industries date back to the stone age flint mines of 2500 bc and still exist. in that period of more than 4,000 years the country's miners have produced colossal amounts of copper, tin, lead, zinc, iron, a lot of silver and some gold, and smaller amounts of just about every other metal from arsenic to uranium. the metals were the foundation of our industrial.
There is a poor understanding of the effect of impurities in phosphate rock on the crystal habit of gypsum during wet-process phosphoric acid production. the present work studies the effects of al3+, sif62-, and f- on the habit of gypsum in an msmpr crystallizer. it is found that the gypsum crystal shape changes little in the presence of al3+ alone. in the presence of both al3+ and f-, the.
