Refining Borax

2004-5-12 · Historically, American borate mining can be divided into three phases: playa surface mining (1860 - 1890), underground mining (1890 - 1957), and open pit mining (1957 - present). The first phase gorged on surface deposits of those borates which were easiest to process, the second devoured large, concentrated subsurface deposits, and the third is

Toward a more sustainable mining future with ...

Metals are currently almost exclusively extracted from their ore via physical excavation. This energy-intensive process dictates that metal mining remains among the foremost CO2 emitters and mine waste is the single largest waste form by mass. We propose a new approach, electrokinetic in situ leaching (EK-ISL), and demonstrate its applicability for a Cu-bearing sulfidic porphyry ore.
