Flotation Overview, Methods, Benefits and Drawbacks

1. Initial Public OfferingOne way to float a company is to issue an initial public offering (IPO), where a private company will go public by issuing shares for the first time. Floating a company using an IPO typically involves an investment bank that undertakes the underwriting process and determines the speci

2. Offer through SaleIn addition to an IPO, a private company can pursue flotation by offering securities for sale using an intermediary, such as a stockbroker. In this case, the issuance of new shares is not available to the public. Usually, a company that pursues such a flotation method is in its early stages of o在corporatefinanceinstitute上查看更多信息发布日期: Jul 01, 2021

60 Centuries of Copper: The Flotation Process

Only the flotation process mentioned above could make this practicable; and even so, it requires large companies with huge plants, continuous working and immense capital. This explains why, in order to smelt 4 million tons of new copper in 1963, nearly 400 million tons of ore had to be handled and treated in various ways.get price
