Stroke ratio Wikipedia
Stroke ratio, today universally defined as bore/stroke ratio, is a term to describe the ratio between cylinder bore diameter and piston stroke length in a reciprocating piston engine A square engine has equal bore and stroke dimensions, giving a bore/stroke value of exactly 1:1 Square engine examples† Volumetric stripping ratio = 27/25 =108 m3 of overburden per m3 ore † Weight stripping ratio = (27 17)/(25 136) = 135 tons of overburden per ton ore † Stripping ratio = 27/(25 136) = 79 m3 of overburden per ton ore Example 2: The head assay of a copper ore is 08% Cu The expected overall copper recovery from the ore is 88%Chapter Open Pit Mining2023年6月15日 Strip ratio (ie, wastetoore ratio), by comparison, was the least important factor contributing to the variation in RMR between operations The factor analysis presented here implies that for most operations, RMRs are governed primarily by the quality of the ore, namely its TREO grade and REO distribution, rather than operational and economic decisions about Rocktometal ratios of the rare earth elements ScienceDirect2020年5月26日 Iron ores consist predominantly of the iron oxide minerals hematite (Fe 2 O 3) and magnetite (Fe 3 O 4)The primary intermixed noniron oxides are SiO 2, Al 2 O 3, MnO, and MgO, and are referred to as gangueBoth pellets and sinter can be produced from a mixture of hematite and magnetite; essentially all the input magnetite is oxidized to hematite when pellets Overview of the Steel Production Process Springer
