Abstract
ในวิธีสำหรับการนำกลับสารเข้มข้นคอปเปอร์ซัลไฟด์โดยการลอยกากจากสินแร่ที่มีไอรอน ซัลไฟด์, ไฮโดรเจนเปอร์ออกไซด์ถูกเติมไปยังพัลพ์เชิงแร่ที่ถูกกำหนดเงื่อนไขก่อนหรือในระหว่างการ ลอย, สารเข้มข้นที่มีออกซิเจนที่ถูกละลายถูกกำหนดในพัลพ์เชิงแร่ภายหลังการเติมไฮโดรเจนเปอร์ ออกไซด์และปริมาณของไฮโดรเจนเปอร์ออกไซด์ที่ถูกเติมถูกปรับเพื่อคงสารเข้มข้นที่มีออกซิเจนที่ถูก ละลายไว้จาก 1 ถึง 5 เท่าสารเข้มข้นเป้าหมายที่ถูกกำหนดไว้ล่วงหน้าเพื่อปรับปริมาณของไฮโดรเจน เปอร์ออกไซด์เพื่อเปลี่ยนในองค์ประกอบสินแร่ In the method for the recovery of the copper sulfide concentrate by flotation from ore containing iron sulfide, hydrogen peroxide is added to the conditional mineral pulp before or during flotation, the substance The concentrated with dissolved oxygen is determined in the mineral pulp after the peripheral hydrogenation. The oxide and the amount of hydrogen peroxide that were added were adjusted to maintain the dissolved oxygen concentration from 1 to 5 times the pre-determined target concentration to adjust the hydrogen content. Peroxides to change in ore composition
