The function GYMass() will calculate the minimum practical sampling weights required at each stage of sampling. The mass given is that obtained by Gy's formula multiplied by a safety factor of 2. For routine sampling, a confidence interval of 95% in the results would be acceptable, but for research purposes, or where greater sampling accuracy ...

simultaneously in order to provide a uniform blend of weight recovery and of product quality (constant silica content). The range of ore weight recovery is 20% to 40%. The concentrate silica content ranges from 27a to nearly 15X silica. These ores are blended to result in a composite analysis of about 6% +/- .2% silica and 30% weight recovery.

(c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from : % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore was lost in the tailings. (d) The % Weight Recovery is equal to the % Weight of the concentrate in Table 1. It can also

For this calculation the iron content of haemoglobin = 0.34%, blood volume = 7% of the bodyweight, and 1,000 is the conversion from g to mg ***Iron depot: <35 kg body weight: iron depot = 15 mg/kg body weight ≥35 kg body weight: iron depot = 500 mg For example a 70 kg with Hb 80 g/L has an iron deficit of: 70 x (150 – 80) x 0.24 ...

The following Iron Ore specifications guide contains the primary specifications and methodologies for Platts Iron Ore assessments throughout the world. These are the timestamps used for Platts iron ore assessments. Data reported at or after these timestamps is not considered in the assessment process. Asia: 5.30pm Singapore Atlantic: 4.30pm ...

cokemaking and iron ore preparation are described in Chapter 3. CO 2abatement from the different iron production routes, namely blast furnaces (BFs), direct reduction processes (which produce DRI) and the smelting reduction processes (which eliminate the need for coking and iron ore sinter plants) are covered in the following three chapters.
