Production is from high-grade uranium deposits in the Shinarump conglomerate of Triassic age. The Shinarump strata range from 16 to 40 feet in thickness and the lower part of these beds fills an eastward-trending channel that is more than 750 feet wide and 10 feet deep.The Shinarump conglomerate consists of beds of coarse- to fine-grained quartz- lose sandstone, conglomerate, siltstone, and Get price

Cut

A cut-off grade (COG) is an industry-accepted standard expression used to determine what part of a mineral deposit to include in a mineral resource estimate (MRE). For MRE reporting, COGs tend to be rounded down to ensure that material of no economic significance is excluded from the resource. Get price

Break Even Analysis

Before I can calculate the cut off grade, I first need to show a basic equation which converts a troy ounce into grams per ton: 1 troy ounce = 31.1034768 grams per ton = 28.349523125 grams per tonne As you can see, the difference between a ton and a tonne is approximately 10%. Get price

Economic Geology of Niobium and Tantalum

Cut-off grade is typically at 100 ppm. Among other applications, scandium is useful as a grain refiner in high-strength aluminium alloys (e.g. in sports equipment), and in solid oxide fuel cells (SOFCs), which convert stored chemical energy (such as hydrogen or hydrocarbons) to useable electrical energy.

Spilpunt: Tantalum

2007/3/17Tantalum market The majority of the world's tantalum is sold by way of long-term offtake agreements between the miner and the tantalum refiner/metal producer. Tantalum is not sold via a regulated market as is for gold, copper, zinc and tin. The global tantalum Ta 2 O 5 market is estimated to be in the order of 4,7 – 5,1 million pounds (approx. 2,200 tonnes) per annum for the years 2005 - 2006. Get price
