Metals from Ores: An Introduction

2019-8-24  shaped grains disseminated in the basalt, characterized of their low carbon content, usually less than 0.7%. These were extracted from the basalt by the natives by crushing and then cold-hammering the collected metallic particles into coin-sized flakes to insert them into groves in bone and use them as knives [3]. Oxides, hydroxides, and carbonates

Thermophysical Properties - NIST

2016-4-4  Sand, ceramic, and metal molds are exten-sively used to cast most metals. During the solidification process, the predominant resis-tance to heat flow is within the mold/metal interface and the mold itself; thus, the primary interest is not the mold thermal history but rather the rate at which the heat is extracted from the solidifying metal.
