| The first step is to calcine the materials and press them into cylindrical rods. |
|
| The kilns that calcine the lime used in cement are often natural gas fired. |
|
| A reverberating furnace with two hearths heated a roaster to 1,200 degrees Fahrenheit to calcine the ore. |
|
| Up again, but a hold flakes under your grip, calcine teeth are chewing at your wrist in the crack, then a toe skates, and like that, poof! |
|
| Project to replace concentrate roasting and calcine smelting with Noranda continuous converter technology has been postponed. |
|
| This was primarily related to the planned 21-day roaster shutdown in February and the resultant lower calcine production. |
|
| The roaster was not affected and continues to operate normally allowing the excess calcine from the roaster to be used at other Nyrstar sites. |
|
| Take some newts, by some called lizards, and those nasty beetles which are found in fens during the summer time, calcine them in an iron pot and make a powder thereof. |
|
| The impresario William Wheatley used lavish sets and costumes imported from Europe and the innovative stage effects included calcine lights and sophisticated machinery. |
|
| Most of the ore is processed in a plant at Dandi, 20 km east of the mine, to produce zinc calcine for subsequent treatment by local refineries. |
|
| Optimisation of calcine distribution across the Group allowed Budel's cell house to achieve record production levels until the decision to move to off peak production in November. |
|
| Specifically, approximately 13,000 tonnes of calcine were received from Auby and Balen to bypass the roaster and fully utilise the cell house capacity. |
|
| The investigation also revealed that the company produced at least in part from zinc calcine it had purchased on the Chinese market and that had to be adjusted as outlined above. |
|
| However, the roaster continues to operate normally and excess calcine that cannot be processed at Auby because of the transformer failure is being transported to other Nyrstar sites where it will be used to produce cathode. |
|
| The process is thermally efficient, and the resulting calcine is in the form of small particles that can easily be leached into solution for further treatment. |
|
| Then I brake the said mixture into suitable lumps and calcine them in a furnace similar to a lime kiln till the carbonic acid is entirely expelled. |
