raction, but also markedly increased lime consumption (e.g. from 20 to 40 kg/t CaO on a flotation middling). Cyanide consumptions were in the range 3–7 kg/t NaCN..Roasting/sulphuric acid leaching/cyanidation, roasting/acid brine leaching/cyanidation, and roasting/sulphuric acid leaching/thiourea lea

Hannes Leitgebs and-non-bonded interactions. Correlation relationships between geometric and vibrational parameters are also presented. It is the metrical aspects of the molecular structure which are primarily considered. Since they correlate with other aspects of the molecular structure, e.g. electronic, it is h

Introduction Philosophy of Mathematics: Old and Newhe right philosophical account of mathematics, examining along the way where they think the philosophy of mathematics is and ought to be going. As one might expect, a rich and diverse picture emerges. Some broader tendencies can nevertheless be detected: there is increasing attention to the practice

New Waves on an Old Beach: Fregean Philosophy of Mathematics Todayatonism — that is, arguments for the existence of abstract objects such as numbers, sets, Hilbert spaces, and so on that comprise the subject matter of mathematics — are either uninteresting or unneeded. Nevertheless, I am not personally interested in such arguments. The reason for this is simple: I

Truth in Mathematics: The Question of Pluralismd led to a plurality of geometries no one of which could be said (without qualification) to be “truer” than the others. In a similar spirit many have claimed that the discovery of independence results for arithmetic and set theory (in the twentieth century) has undermined the claim that there is one
