The minerals are galena, copper pyrites, iron pyrites, and zinc blende.
Sayfa 167 - The minimum requirements for tensile strength for briquettes one inch square in section shall be within the following limits, and shall show no retrogression in strength within the periods specified: ' Age Neat Cement Strength 24 hours in moist air 150 — 200 Ibs.
