Nov 13 2020· The surface dissolution of apatite in the flotation pulp will change the surface properties of minerals and the chemical environment of flotation pulp In general the silica sand is easily activated by Ca2 under the alkaline conditions pH > 10 so the dissolved Ca2 in the apatite solution will have an adverse effect on the separation of
JXSC Mine Machinery Factory Mining provides a variety of mining equipment and mineral processing equipment for equipment not only applied in large mining plants but also suitable for small scale metallurgy operations operated by small miners whether you are making big business in the mineral industry or a small one even you are just a hobbyist miner or mining fanatics
Apatite is a group of phosphate minerals usually referring to hydroxyapatite fluorapatite and chlorapatite with high concentrations of OH − F − and Cl − ions respectively in the formula of the admixture of the three most common endmembers is written as Ca 10 PO 4 6 OH F Cl 2 and the crystal unit cell formulae of the individual minerals are written as Ca 10 PO 4 6
Jan 01 1988· The cone classifier underflow is fed back to the ball mill and the overflow goes to flotation In the older line both the mills are 4 m diameter x 6 m with 1700 kW motors In the newer line the rod mill is m diameter x m and the ball mill m diameter x m with 1700 kW and 2 x 1700 kW motors respectively
The classifier overflow was pumped to storage tanks prior to leaching First leaching stage —The feed material contained 4% % V 2 O 5 and 18% Zn Because a high zinc content would result in high leaching activity of zinc and inefficient vanadium solution a zinc content in the solution below 100 125 g/L was preferable
Sep 01 2020· In the suggested industrial scale processing of Keliber Oy s spodumene pegmatite ore the ore is first subjected to grinding with a rod mill and the classifier overflow is then further ground in a ball mill Keliber Oy 2019 The ground ore is deslimed and conditioned in basic solution adjusted by NaOH prior to the pre flotation stage which is used to remove apatite from the feed to
