Columbia Pulp has the lowest carbon footprint by a significant margin within the pulping industry. There are three main reasons: 1. Usage of a genuine waste product (straw left over from wheat farming) 2. Wheat straw is a locally sourced product for our facility, providing a resourceful supply chain 3.
26-07-2017· Carbon is advanced such as to satisfy daily production requirements. An adequate amount of fresh or reactivated carbon is added daily to the last tank in the circuit. Carbon concentration in the pulp averages 24 grams of carbon per liter of pulp. Carbon loading, expressed in grams per metric ton of carbon is shown on Table 2.
Biopolymers that have been reinforced in this way are called biopolymer composites. The table below is a summary of some common biopolymer composites, their properties and the industries in which they are already widely used. Table 2. Summary of biopolymer composites production methods, properties, and applications [6].
INTRODUCTION Carbon-in-pulp (CIP) technology which has developed rapidly since 1974 is now accepted as an economically and technically viable process for the efficient recovery of gold. This paper describes testwork and flowsheet development procedures used for CIP evaluation and design.
Black liquor lignin from the pulp and paper industry can be used as a precursor for activated carbon. The lignin is carbonized in an oxygen-free atmosphere and the resulting carbon is then activated with steam. The resulting lignin-based activated carbon is considered to have the potential for use in …
The pilot plant test work was carried out utilizing a 1.7 m3 pump-cell. The pilot plant testwork indicated the following: The carbon-in-pulp effectively recovered gold from the West Driefontein repulped slimes dam material Significant amounts of wood fibre necessitated the upgrading of pre-screening Extra gold dissolution of approximately
