However, high siliconcontaining lignocelluloses are generally not preferred for pulp and paper manufacturing because they may causes several damages for cooking, bleaching, and washing devices On the other hand, bagasse had the following levels of the elemental contents: carbon (C) 4296%, oxygen (O) 5429%, aluminium (Al) 009%, silica (Si) 023
Carboninpulp processes in South Africa ScienceDirect
Hydrometallurgy, 13 : 169 192 The carboninpulp (CIP) process is now well established in the South African gold industry, with a total of over 1 million metric tons of material being treated each month in six large plants This tonnage is derived from ground ore, from filtered pulp, from cal cine, and from reclaimed sandtailings dumps
Carbon in pulp
Carbon in pulp (CIP) is an extraction technique for recovery of gold which has been liberated into a cyanide solution as part of the gold cyanidation process Introduced in the early 1980s, Carbon in Pulp is regarded as a simple and cheap process As such it is used in most industrial applications where the presence of competing silver or copper does not
CarboninPulp ScienceDirect
By replacing the Merrill–Crowe zinc cementation step, carboninpulp (CIP) and carboninleach (CIL) recovery provided a process that allowed the treatment of lower grade and problematic ores, Highquality experimental data are required in order to make effective use of models and simulations (Stange, 1999)
