Barite and its effect on the solids control system. Barite is used to weight the mud in intervals where a heavier mud is needed. However, the weight of barite impacts the solids control system and affects the speed and number of centrifuges needed to remove ultra-fine cuttings. Typically, one centrifuge is used for mud weights lighter than 12 ...

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Because barite forms in association with organic material, there is a tight correlation (r 2 =0.93) between the sedimentary fluxes of carbon and barite (Dymond et al., 1992). Thus, barite accumulation rates have been used to infer past levels of export production in the ocean (e.g., Dymond et al., 1992; Paytan et al., 1996).

The milling process requires a milling machine, workpiece, fixture, and cutter. The workpiece is a piece of pre-shaped material that is secured to the fixture, which itself is attached to a platform inside the milling machine. The cutter is a cutting tool with sharp teeth that is also secured in the milling machine and rotates at high speeds.

Barite is ubiquitous and known to incorporate 226Ra through the formation of a solid-solution. In U mining mill tailings, barite is one of the dominant sulfate-binding minerals. In such environments, sequential extractions are generally used to identify the U- and 226Ra-binding phases and their associated reactivity. To better decipher the main processes governing the …
