Minsheng brand D301G gold extraction special resin

Minsheng brand D301G gold in special resin Product Description I. Introduction: D301G macroporous polystyrene skeleton weakly basic anion exchange resin containing -n (ch3) 2, alkaline weaker than strong base resin, easy to regenerate Working strong base exchange capacity is three times, resistance to organic contamination. Using unique technology and a, which has high mechanical strength and chemical stability of cyanide Asian gold complex has a special selective absorption speed, absorption capacity, mainly used in gold extraction. Second, performance indicators: Appearance light yellow transparent sphere Functional group -n (ch3) 2 Total exchange volume ≥4.8mmol / g dry volume exchange capacity ≥1.4mmol / ml Water 50% to 60% 15 to 20% Swelling really wet density 1.03 ~ 1.07g / ml Shipping weight 0.65 ~ 0.72g / ml size range 0.6 ~ 1.6mm maximum use temperature oh40 ℃, ci100 ℃ After the ball mill rate ≥95% three reference operating conditions: The maximum operating temperature oh40 ℃, ci100 ℃ Resin filled with a high degree of 1 ~ 3m Operating velocity 2 ~ 10bv / h backwash flow rate of 4 ~ 10bv / h regeneration (desorption) Flow 1 ~ 2bv / h regeneration dosage 2bv3 ~ 5% hci, 2bv2 ~ 4% naoh Note: Photos for reference only, in kind or samples prevail.
