Q1: Why is hardness critical for gold recovery carbon?
A: CIP/CIL circuits involve intense agitation and inter-particle abrasion. Soft carbon generates fines that carry gold through screens, causing recovery loss. PLC-480's >98% hardness minimizes attrition, maximizing gold retention and simplifying carbon transfer operations.
Q2: What is the typical carbon inventory cycle in gold recovery?
A: Carbon moves continuously: fresh carbon enters CIP tanks, loads gold over 8-24 hours, transfers to elution for gold stripping and thermal regeneration, then returns to circuit. Complete cycle typically 24-48 hours depending on plant design and solution grade.
Q3: Can you provide samples before bulk order?
A: Yes, samples can be given to you. Please contact us for details. Once we charge you the sample fee, please rest assured that this will be a refund when you place a formal order.
Q4: What is your minimum order quantity (MOQ)?
A: MOQ depends on product type. Please contact us for detailed information.
Q5: How long is the delivery time?
A: Normally 15-30 working days depending on order quantity and production schedule.
Q6: How to confirm payment?
A: We accept T/T ,L/C, and other payment methods are also acceptable. Please contact us before you make payment through other payment methods. In addition, a deposit of 30-50% is feasible, and the balance shall be paid before shipment.
