Question

Никелевая руда содержит 1,3 % никеля. Сколько тонн никеля получится из 24,860 т руды ? Сколько тоннэтой руды надо переработать чтобы добыть 2405 т никеля

Answer 1

1) 24,860  * 0,013 = 0,32318 (  тонны ) никеля ( или 312 кг )
2) 2405 * 100 : 1,3 = 185000 (   тонны ) руды надо переработать
   

Answer 2

Calculating Nickel Content in Ore

To calculate the amount of nickel in the given amount of nickel ore, we can use the following formula:

Nickel content = (Percentage of nickel in ore / 100) * Total amount of ore

Given: - Percentage of nickel in ore = 1.3% - Total amount of ore = 24,860 tons

Using the formula: Nickel content = (1.3 / 100) * 24,860

Calculating the nickel content: Nickel content = 0.013 * 24,860 = 323.18 tons

So, the nickel content in 24,860 tons of ore is approximately 323.18 tons.

Amount of Ore Needed to Obtain 2405 Tons of Nickel

To find out how much ore is needed to obtain 2405 tons of nickel, we can rearrange the formula to solve for the total amount of ore:

Total amount of ore = (Desired amount of nickel / Percentage of nickel in ore) * 100

Given: - Desired amount of nickel = 2405 tons - Percentage of nickel in ore = 1.3%

Using the formula: Total amount of ore = (2405 / 1.3) * 100

Calculating the total amount of ore needed: Total amount of ore = 184,230.77 tons

So, approximately 184,230.77 tons of ore are needed to obtain 2405 tons of nickel.
