If the limestone grade is almost high and contains above 90% CaCO3, then in direct flotation more reagent is required for collecting all limestone mineral. But if u r not concern about reagent cost, the no problem. Yes u can use oleic acid as a collector and sodium silicate is depressant for silicate minerals.
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.

One way is to crush the limestone to −3 mm size and then to process it in a scrubber and classifier. Another entails grinding the raw feed to less than 200 mesh and then to carry out beneficiation by a froth flotation method,,, . In the present case, a low grade limestone sample was processed using the column flotation technique.

Froth flotation of scheelite – A review - ScienceDirect. More often than not, scheelite undergoes the so-called "lime flotation process", where sodium carbonate and sodium silicate are used as modifiers after the addition of lime and sodium oleate as the main collector,, .
cross exchange of flotation experience in the mineral flotation and water effluent treatment should lead to new and improved procedures for industrial waste treatment . The flotation process has enabled the production of high brightness . calcium carbonate by removing the silicate impurities from the
The Problem with Calcite Processing & Flotation The availability of high lime rock is often limited and it becomes necessary to use lower grade sources from quarries favorably located to cement plants. Beneficiation of the lime rock in such cases is necessary to remove impurities and to secure the proper ratio of calcite to other constituents for cement specifications.
The chemical name for the substance of quartz is silica; and any mineral that is composed in part of silica is a silicate. In the Classification of Silicate Minerals and the study of minerals and rocks, silica is called an acid; in silicates, the substances other than silica are called bases, for example, lime, potash, and soda. When giving the full name of a silicate the names of these bases ...
