[Music] the world gold Council WGC is a representative organization of the global gold mining industry providing guidance standards and research to promote responsible gold mining their mission is to ensure that gold is mined and produced in a safe sustainable environmentally responsible manner that Ben benefits local communities over the long term the WGC conducts extensive research on the gold market providing information and Analysis to investors governments and other organizations the current gold mining and processing process involves many complex steps from determining the gold reserves in a mine to producing pure gold ready for the market before mining begins member companies will conduct detailed geological surveys to determine the gold reserves and assess the environmental impact geologists will use methods such as exploratory drilling magnetic field measurements and soil analysis to better understand the reserves and characteristics of the gold mine mining must comply with local laws and international standards companies must apply for mining permits and conduct detailed environmental impact assessments to ensure that the mining process does not harm the natural environment and public health there are two main methods of gold mining open pit Mining and underground mining open pit mining applies to mines with ore close to the surface Rock and soil are removed to expose the gold bearing layers which are then transported to a processing area meanwhile underground mining is used for mines deep underground tunnels are dug to access the ore which is then transported to the surface once the gold ore is mined it is crushed and subjected to further processing steps to separate the gold processing usually involves methods such as cyanide treatment and carbon in leech sill or carbon in Pulp CIP cyanidation method is the most common method gold ore is dissolved in cyanide solution the gold is then separated from the solution through absorption meanwhile in Cil or CIP method The Ore is immersed in cyanide solution then the gold will stick to carbon particles making it easy to separate the gold from the solution these methods strictly follow the safety and environmental control standards set by the world gold Council and international organizations to ensure that chemicals such as cyanide do not negatively affect the ecosystem the crude gold after being separated from the ore will be sent to the smelter to remove impurities and achieve the desired Purity usually 99. 5% or higher this process includes two steps smelting and refining the gold is heated at high temperatures to remove impurity Metals such as silver copper electrolytic or chemical methods can then be used to achieve the highest Purity resulting in a pure gold product ready for the market after refining the gold is cast into bars or coins of the required size and Purity the gold products are then carefully packaged for shipping to Banks jewelry manufacturers or investment institutions around the world the world gold Council requires its member companies to adhere to International standards they are required to set guidelines to ensure that mining activities are environmentally friendly responsible to local communities and comply with international law companies regularly test the quality of water air and soil in the mine area to ensure there is no pollution or negative impact on the living environment companies are encouraged to invest in infrastructure education and health Health projects in the areas surrounding the mind helping to improve the lives and create jobs for local communities the modern gold mining and production process supported and monitored by the world gold Council includes many steps from prospecting permitting mining processing to refining and minting gold they are committed to supporting companies to conduct responsible safe and sustainable gold mining ensuring that gold is mined and produced to the highest standards benefiting communities and protecting the environment [Music] [Music] [Music] [Music] [Music] [Music] Planet gold Guyana is part of a global initiative to promote sustainable artisanal and smallscale gold mining asgm particularly in eliminating Mercury from the mining process Planet gold Guyana has been introducing state-of-the-art equipment such as the gold katcha gold Cube and blue Bowl to replace the traditional method of gold mining that uses Mercury why is mercury needed Mercury is an extremely toxic substance that is seriously harmful to human health and the environment the use of mercury and gold mining has caused many unpredictable con consequences including water land and air pollution affecting the health of people and living things to address this problem Planet gold Guyana has introduced new gold concentrators that do not use mercury below are details of each type of equipment the first equipment is the gold katcha gold katcha is a portable gravity concentrator designed to recover gold from ore without the use of chemicals or Mercury it is ideal for aluvial Minds because of its ease of use and ability to achieve High Purity it uses water flow and vibration to separate heavy gold particles from soil and sand the gold particles will settle to the bottom of the tray while the lighter particles will be washed away by the water flow what needs to be done is to put the gold ore or aluvial into the machine after screening to remove impurities and large rocks The Ore is fed into the gravity rotating chamber of the machine under the action of centrifugal force the heavier gold particles will settle to the bottom while the lighter impurities will be pushed out the gold will then be separated allowing the miner to obtain pure gold with high recovery without adding any chemicals the advantages of this equipment are simple design easy to use and maintain high efficiency in Gold extraction from aluvial deposits with large gold particle size and low investment cost however the efficiency of gold extraction may be reduced when the gold particle size is too small or when the gold content in the ore is low the second device is the gold Cube the gold cube is a multi-stage concentration system using the principle of sedimentation and flow to retain gold this device is suitable for small gold mining operations where miners can recover gold from aluvial deposits effectively to use this device The Ore material will be screened to achieve a small size usually less than 1 mm which helps increase the efficiency of gold extraction the material will be passed through many layers of the gold Cube where the gold will settle on the concentration plates according to the principle of gravity the lighter impurities will be pushed up and out after the concentration process is complete the gold will remain on the filter plates miners only need to recover the gold from these filters to achieve good results without using mercury this device is highly efficient in separating gold from various ores providing the ability to separate gold with small particle sizes however the disadvantage of this device is that the investment cost is higher than that of gold katcha the third device is the Blue Bowl the blue bowl is a dis type gold separator which uses a Vortex of water to concentrate and recover gold this is a simple and easy to use device suitable for separating pure gold from aluvial Sand especially with very small gold particles we need to ensure that the ore has been finely ground and large impurities removed then put the raw material Into the Blue Bowl and adjust the water flow accordingly creating a gentle Vortex to help the Gold Settle to the bottom of the bowl the gold particles due to their heavy weight will automatically settle to the bottom of the device while the lighter sand particles are swept out the gold katcha gold Cube and blue Bowl devices help miners recover gold effectively from aluvial mines without harming the environment and health with Planet gold guyana's approach they are committed to supporting smallscale gold miners in adopting mercury-free methods that are economically viable safe and sustainable [Music] African gold Refinery AGR is one of the largest gold refineries in East Africa located in Uganda AGR carries out the process from raw material procurement to the final product ready for the market this raw gold can be in the form of gold ore or gold dust which is low in Gold content and unrefined each batch of raw gold is Thoroughly tested before being put into production
