1. Plan Your Release. The first step in a successful release management process is, unsurprisingly, to plan the release. The details of how your organization approaches release planning depend on the specifics of your software development process. For instance, agile shops will plan releases according to approved user stories.

Abstract. The flotation processing characteristics of pervoskite, ilmenite and rutile from igneous and sedimentary ores were examined in the course of developing a commercial treatment process. Flotability of these minerals was found to be strongly influenced by a) flotation pH, b) pulp treatment before flotation, and c) type of collector.

Ilmenite Composition: Ferrous titanate, FeTi03. Fe = 36.8 per cent, Ti = 31.6 per cent, O = 31.6 per cent. By the introduction of ferric oxide, the ratio between the titanium and iron often varies widely. The excess of ferric oxide may be largely due to minute inclusions of hematite. Magnesium may replace the ferrous iron.
