📓 Книга "Gold Assaying. a Practical Handbook Giving the Modus Operandi for the Accurate Assay of Auriferous Ores and Bullion and the Chemical Tests Required in the Processes of Extraction by Amalgamation, Cyanidation and Chlorination : With an Appendix of Tables".Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.
