Panda, N.K. Sharma and S.K. Gotecha National Council for Cement and Building Materials (NCB), New Delhi, India. Abstract
In this paper, a value in use model based on mass balance and heat balance was developed and used to evaluate the impact of lime quality on the BOF process.
An Indian limestone beneficiation plant employs various processes, including crushing, screening, scrubbing, grinding, and classification. It includes the development of commercially viable techniques for lowering the mass of gangue minerals [11]. In the context of flotation, the process involves treating a mixture of finely ground ore

A low grade Limestone from ACC mines, Madukkarai, Coimbatore district, Tamil Nadu, India, was subjected to beneficiation by cationic reverse flotation process with the aim of producing cement grade and metallurgical grade concentrates. The low grade limestone analyzed 43% CaO, 76%TC, 18% SiO 2, 1.3% MgO, 1.30% Fe 2 O 3 >, 2.50% …
Beneficiation of a siliceous limestone sample Summary: White colored low grade siliceous limestone sample containing 45.10 % CaO and 15.60 % SiO2 from the Jayantipuram mine of Andhra Pradesh/India has been investigated for amenability to beneficiation by flotation. The limestone sample was crystalline and consisted mainly of calcite and quartz.
