separation of copper hydroxide from calcium chloride

Separation and recovery of copper, nickel, cobalt and zinc ...

2012-10-1  The extraction of manganese and calcium was negligible. With the feed solution containing 200 g/L calcium chloride, high copper extraction and low nickel extraction were obtained. The separation factors of copper over other metals in the range of CaCl 2 concentrations studied are shown in Table 2.

Lab #2 PHYSICAL SEPARATION TECHNIQUES Introduction

2010-8-26  3.(4 points) A student is given a 6.216 g mixture of iron filings, calcium chloride and sand. He separates the mixture and recovers 2.524 g of iron, 1.932 g of sand and 1.523 g of calcium chloride. Calculate the percentage of each component he recovered from the original mixture and the percent of material he lost during the separation process.

Etching with Air Regenerated Acid Cupric Chloride

2005-11-5  This method involves adding lime (calcium hydroxide) directly to the cupric chloride etching solution. The copper is converted to hydroxide, just as it would be if sodium hydroxide was added, however the reaction with calcium is much less violent, and the sludge formed is a lot less liquid. When the lime is initially added the acid will first ...
