Excerpt from The Enrichment of Ore Deposits The problems of superficial alteration and enrichment are not simple. Not only do the several metals segregate in different ways, but each metal may behave differently in different mineral associa tions. Every district and every deposit should be studied separately in the light of all available chemical and geologic data. There are, however, certain laws Of segregation that almost invariably are clearly indicated, and as data have accumulated many puzzling ap parent exceptions to these laws have disappeared. This paper is an amplification of, an earlier Survey bulletin on the enrichment of sulphide ores (bulletin It is a discussion of representative deposits, especially Of the paragenesis of their ores and of the principles that underlie the processes of enrichment. I hope it may suggest to those engaged in geologic work and in mining some lines Of approach to the solution of the complex problems that are encountered in the field. I realize fully that there may be serious omissions and possibly errors in the discussion of the complex problems here presented. I shall esteem it a favor if anyone whose statements I may have mis quoted or misinterpreted will set me right, and if those who have had superior opportunities for study Of certain districts will correct any wrong impressions that I may have given.
