Organic affinity of silver in subbituminous Assam coals

Silver has been identified for the first time in high sulphur coals of Assam, India. Its total concentration varies from 55–60 microgram / gm and dominantly associated with the organic fraction (>81.8%) in non-exchangeable form. Knowledge gained from this study will be helpful to predict geo-chem...

Description
Summary:Silver has been identified for the first time in high sulphur coals of Assam, India. Its total concentration varies from 55–60 microgram / gm and dominantly associated with the organic fraction (>81.8%) in non-exchangeable form. Knowledge gained from this study will be helpful to predict geo-chemical principles involved in association of silver with geological substrate.
