该精矿初始熔点高，生成液相量少，烧结矿矿物组成复杂，严重影响强度与冶金性能。
The strength and metallurgical properties were affected severely as sinter liquid was less and complex mineral composition owing to high melting temperature point of concentrate.
研究内容主要包括：借助矿相显微镜、扫描电子显微镜、压汞仪等工具对烧结矿的矿物组成及显微结构进行研究；
The research was focus on the following aspects: the study of mineral composition and microstructure of sinter by OM, SEM, mercury intrusion machine etc;
铝酸钙熔剂可由各种矿物组成。例如：石灰(或石灰石)和铝土矿(或铝)，并且有不同的形态(如：烧结态或熔态)。
Calcium aluminate fluxes can be produced from various mineralogical precursors such as lime or limestone and bauxite or aluminum dross, and in different physical forms such as sintered or fused.
