A local welding torch cutter busy demolishing the cones cut through a section on which he was sitting. He fell off, followed by the section he was cutting. This section severed his leg when it hit him.<br />Shortage of iron mill balls (Forex problem)meant that every piece of scrap was salvaged and sent down to the foundry near Kitwe to cast into mill balls.<br />I was General Foreman/Assistant Superintendent A (Leach, Solvent Extraction and Tailings) 1978/9 before moving over to Ndola Lime Company Anonymoushttps://www.blogger.com/profile/04553677472342050230noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-6634613912068311042012-12-10T16:09:21.131+00:002012-12-10T16:09:21.131+00:00I finally caught up with Tom Whitehouse via the bl...I finally caught up with Tom Whitehouse via the blog.

Roy Jeffries was a friend of mine in my late teens- we attended the same youth club in Northern England, both studied metallurgy at different Universities, then went our separate ways to Zambia. I believe he is now retired in the Manchester area.<br />Is your Mr. Williams Geoff Williams? If so, he was metallurgical superintendent at Nchanga in the early 70s.MEIhttps://www.blogger.com/profile/14834780351452765156noreply@blogger.comtag:blogger.com,1999:blog-6908362959739425575.post-79415533120391037562011-07-26T21:56:22.873+01:002011-07-26T21:56:22.873+01:00TLP is a complex metallurgical plant consisting of...TLP is a complex metallurgical plant consisting of primary and secondary leach circuits, a dewatering section (thickeners, clarifiers and HBFs), a high profile solvent extraction plant (series-parallel flow configuration) and an electrowinning circuit. By 1988, TLP had a staff complement (Technical, Engineering, Operations and Services depts.) of about 2400 operatives. Total solids throughput to TLP was about 46 000 tpd (reclaimed and current flotation tailings) and copper cathode production ranged between 2600 - 3000 tpd. Mr Jim Mawer was the Production Superintendent when I joined and he was succeeded by Mr Roy Jeffries and later Mr Williams (I wish I knew where these men are now). The Kennecott cone precipitators were decommissioned immediately after bringing online the solvent extraction and HBFs (Horizontal Belt Filters) plants. Dr Barry Wills (MEI editor and author had worked at TLP in the 70s). The company has changed mine proprietors several times but it is currently under the LME-listed Vedanta Resources plc operated by KCM Ltd (Konkola Copper Mines, Ltd). For the purpose of treating low grade copper deposits and refractory ores in a feasible and sustainable manner, KCM Ltd has commissioned an acid manufacturing plant and copper smalter plant partly to support TLP operations.<br /><br />Henry Kasaini, Tshwane University of Technology, South AfricaAnonymousnoreply@blogger.com
