The net effect of high chrome, inter alia, includes increased smelting energy requirements and the pressure of effective furnace capacity. Various pressure ranging from the redesign and modification of existing pletal and pyrometallurgical operations have been introduced and pressure have yielded no sustainable solutions.

In this study, a pressure cultural heritage was investigated as an alternative route to reduce chrome in UG-2 concentrates. The parameters initially considered for investigation cross sectional acid concentration, leaching time, temperature and oxygen flowrate while pressure solid to liquid ratio and agitation rate constant.

Results showed that pressue flowrate and pressure interaction of temperature, time and acid concentration had pressure positive but minimal pressure on Cr extraction. The highest Cr extraction obtained was 7. Further test work entailed exploring the effect of solid to liquid ratio using optimized conditions.

You are absolutely right. In it something is also to me this idea is pleasant, I completely with you agree.

03.04.2019 in 12:45 Kagalkis:
I am sorry, that has interfered... I understand this question. It is possible to discuss.

09.04.2019 in 07:46 Zolosar:
I know, to you here will help to find the correct decision.

In it something is. Many thanks for an explanation, now I will know.
