  • History of Gold-Mining in Ghana
    a very scientific manner recorded historical political economical and social developments in West Africa and in the sub Sahelian areas Over the last 500 years the advent of European traders missionaries and adventurers produced written records of events they encountered during their more or less long ventures at the shores of the West Coast Of course a lot of information they gathered and laid down in their records was based on hear say sources because only very few adventurers penetrated the hinterlands Nevertheless we will realise that all these records as one sided and biased they might be in many cases together with oral tradition culled from the traditional rulers and archeological evidence can form a quite solid basis for the reconstruction of historic events in West Africa in general and the area of today s Ghana in particular Completely different is the picture for the earlier times i e before 1000 A D for the three millenia back to 2000 B C We are very certain that negroid ethnics were populating the West African lands but we do not know where they came from how they called themselves which political and socio economic systems they had developed for themselves and whether or when they perished migrated away or were absorbed by other negroid ethnic groups who themselves migrated from almost uncertain directions into these tropical rainforests In short whilst we can speak of the Bono Gyaman Guan Asante for the last millenium we can only call the previous inhabitants the black West African sometimes differentiated according to distinct cultures named according to the location of their archeological finds like Ntereso Nok Benin etc These sites prove the existence of highly developed cultural and technical skills expressed in the overcome artefacts found in the excavations But the curtain in respect

  • THE TETREM SMALL MINE
    and companies and should therefore contribute also to economic development of the hinterland Some of these orebodies as well as the ubiquitous gold bearing alluvials are currently mined by artisanal small scale miners commonly called galamsey which use manual labour only and employ simple handtools in their operations A visit to such operations will convince any observer that in almost all cases the operations are either inefficient including the skimming of orebodies or dangerous or environmentally unsound or a combination of these This is due to the long oppression of small scale mining activities first by the Colonial Government from about 1920 ongoing later by the Ghanaian authorities after Independence Only in 1986 under the Minerals and Mining Law PNDC Law 153 was the small miner legally recognized and a basis laid for his operations Vast experience in narrow vein mining which was available among African small scale miners before and around the advent of this century has been lost To prove this point mention should be made of the African engineer T B F Sam who managed and operated singlehandedly the Adja Bippo Mine near Tarkwa before 1900 the only mine of all the mines in operation since 1880 which was profitable and declared dividends Rosenblum 1974 Today it can still be assumed that there will be no re juvenation of skilfull vein mining by African small scale miners as long as it has not been proved to Ghanaian investors that such operations could be viable The proof can be presented best by a few reference operations applying durable locally available machinery simple and sound mining and extraction methods basic safety standards and bearable working conditions as well as in their effect on the environment controlled operations Such reference mines could also provide the necessary information in respect of

  • Gold Ore Treatment at Tetrem Small Scale Mine
    in detail the mining safety and environmental aspects of the venture At Tetrem various experiments with different machinery for crushing and grinding the ore in preparation for gravity separation sluicing were carried out and the results are presented The trials led to the construction and application of suitable locally obtainable equipment for such milling operations Continuous weighing and sample checks at the different stages of the comminution and gravity separation provided interesting production and recovery data which could be of help for similar operations Trials for improved recovery of gold from sulphidic ores were carried out and showed the restrictions of gravity separation when confronted with such fresh ores The amalgamation process recirculation of tailings special handling of tailings for recovery improvements are described An overview about the results obtained during six months of operation is presented Improvements for the locally produced machines and problems with maintenance and repairs of the equipment as well as strategies to solve them are discussed The experiences obtained in the marketing of the final gold product are critically outlined de dc subject gok ZU 000 de dc title Gold Ore Treatment at Tetrem Small Scale Mine de dc type article de dc subject gokverbal Bergbau Technik de dc type version draft de dc rights holder Andreas Peters MSc MBA de dc description notes My brother still wanted to publish this magazine article at the 15 05 2001 before his death Unfortunately it was not granted to him any more to do this I have sighted his estate and processed according to these as his brother Therefore I am publishing the last work of my brother Dipl engineer Winfried Peters now too so that his bequest is filled I unfortunately can not guarantee for the scientific correctness of the work however have revised this work

  • Operation and Cost Analysis of a Partly Mechanized Small Scale Gold Mine in Ghana
    to alluvial gold deposits and on limited scale to hard rock occurrences The need to initiate and operate partly mechanized small scale mines stems from the existence of many small orebodies spread all over Ghana which are in their extent and amount of available ore reserves too small to be of interest to medium or large scale mining companies In this presentation one of these small auriferous orebodies is described and the operation of a small mine is outlined The employed mining methods during start up and throughout production phases are described Special attention is given to safety aspects of such operations A mechanised plant for crushing and grinding the ore in preparation for gravity separation sluicing was set up by using locally obtainable or manufactured crushing seeving and milling equipment The extraction results over 6 month operation are presented and discussed The total investment for the small mine and the production costs are presented giving an overview on the economics for such operation Factors to be observed to safeguard a small mine from causing adverse environmental effects are discussed Finally an outlook in respect of multiplication of such operations in Ghana is presented de dc subject gok ZU 000 de dc title Operation and Cost Analysis of a Partly Mechanized Small Scale Gold Mine in Ghana de dc type article de dc subject gokverbal Bergbau Technik de dc type version draft de dc rights holder Andreas Peters MSc MBA de dc description notes My brother still wanted to publish this magazine article at the 15 05 2001 before his death Unfortunately it was not granted to him any more to do this I have sighted his estate and processed according to these as his brother Therefore I am publishing the last work of my brother Dipl engineer Winfried Peters
