Estimation of gold inventory in large carbon in …
A gold ore processing plant that processes 2000 t/d of a gold ore assaying 7 g/t may have a gold inventory of more than 140,000 g of gold in gravity concentrator bins, carbon in pulp tanks and in the electrolysis circuit. This is equivalent to the mass of gold that fed the circuit during 10 days of operation. The change of inventory may therefore strongly impact on the production figures and ...
Carbon Pools and Measurement Frequency for …
A carbon inventory, for carbon mitigation as well as forest conservation and land development programmes and for greenhouse gas inventory programmes and projects, requires estimation of stocks of carbon pools in biomass and in soil for a given period. There are five carbon pools, and measurement, monitoring and projection of changes in stocks of carbon in all the five carbon pools …
ACTIVATED CARBON IN GOLD RECOVERY - Kemix
This article serves to discuss the fundamental aspects of gold recovery utilizing the Carbon-in-Pulp or Carbon-in-Leach processes. The purpose is to describe in simple terms what activated carbon is all about and how it adsorbs gold. The understanding of the mechanism of gold adsorption is important because the CIP/CIL processes work as
CARBON CONCENTRATION MEASUREMENT AND CONTROL IN A …
concentration-meter to measure carbon concentration in pulp. The meter uses an ultrasonic measurement technique. Long term testing has shown the measurement to be robust and require minimal maintenance. Results from a gold mine in South Africa’s well known Witwatersrand gold producing area has shown a decrease in soluble gold loss between 30 – 50% when the controller …
What is the Carbon inventory? – Jean-Marc …
Once the overall carbon inventory is done, part of the possible reductions will directly concern suppliers. It might be relevant to ask the suppliers to assess their greenhouse gases emissions, try (hard) to reduce them, and in he end it will even be possible to change suppliers to decrase the “greenhouse cost” of the production, just as decreasing the financial cost is often a reason to ...

The process design of gold leaching and carbon-in-pulp ...
gold plant will be that of the leaching and carbon-in-pulp circuit (CIP). The reagent and utilities operating costs associated with leaching, adsorption, elution and regeneration would typically make up some 15% of total operating cost, whilst the capital costs associated with these areas is about 16% of the total. Although not largest (capital and operating costs associated with comminution ...
Factors influencing the rate of gold cyanide …
Consequently, the carbon concentration in the pulp can be five times less in CIL than in CIP for an equivalent carbon inventory in the plant, and this translates into increased pumping costs when carbon is advanced through the circuit, and increased back mixing of pulp, when pulp with a low concentration of gold is pumped up the circuit into a tank with a higher gold content.

Metallurgical process - DRDGOLD
The Ergo operation currently has two metallurgical plants in operation: ... The dissolved gold is adsorbed onto activated carbon, and the ‘loaded carbon’ in each circuit enters the carbon treatment section where the gold is eluted from the carbon. The carbon then returns to the CIL circuit via a regeneration kiln. Once the gold has been eluted, it undergoes a process called electro-winning ...
