Abstract
DC60 (20/08/57) กรรมวิธีของการเปลี่ยนเป็นแร่ธาตุของแคลเซียมจากของเสียจากอุตสาหกรรมซึ่งประกอบด้วยการสกัด ไอออนแคลเซียมจากสารแขวนลอยของอนุภาคแบบเม็ดที่มีแคลเซียมเป็นส่วนใหญ่และเอเควียสแอมโมเนียมไนเตรต ในรูปแบบส่วนแรกที่มีแคลเซียมเป็นส่วนใหญ่และส่วนหนักเป็นส่วนที่สอง ส่วนหนักส่วนที่สองถูกแยกจาก ส่วนแรกและส่วนแรกที่มีแคลเซียมเป็นส่วนใหญ่ถูกคาร์บอเนตกับแก๊สที่มีคาร์บอนไดออกไซด์ให้อยู่ในรูปแบบ สารแขวนลอยของแคลเซียมคาร์บอเนตตกตะกอนและเอเควียสแอมโมเนียมไนเตรต ส่วนที่ตกตะกอนถูกแยกออกจาก เอเควียสแอมโมเนียมไนเตรตโดยวิธีการใช้แรงเหวี่ยงหนีศูนย์กลางและแยกส่วนหนักส่วนที่สองที่ประกอบด้วย เปอร์เซ็นต์โดยน้ำหนักของเหล็ก DC60 (20/08/14) A process of mineralization of calcium from industrial wastes consisting of extraction. Calcium ions from granular suspension with predominantly calcium granular particles and ammonium nitrate Aqueous. The first portion contains mostly calcium and the second heavy. The second heavy part was separated from The first and predominantly calcium-containing parts are carbonated with carbon dioxide gas to form Precipitated Calcium Carbonate Suspensions and Akvias, Ammonium Nitrate The precipitated part is separated from Ammonium nitrate acuvius by means of centrifugal force and heavy separation. Percentage by weight of iron
